“The Chronicles of Narnia: Prince Caspian” raked $56.6 million in its opening weekend. It was enough to unseat “Iron Man” from its perch atop the box office mountain, although the comic-book film still brought in $31.2 million, bringing its 3-week total to an impressive $222 million. “What Happens in Vegas” made a strong $13.9 million in it second week out, and “Speed Racer” ($7.6 million) continued to disappoint.

In television, America is still fond of “American Idol” and “Dancing With the Stars,” both concluding this week. Nielsen ratings are here.

Neil Diamond sits atop the Billboard 200 and the UK charts for the first time, well, ever. Toby Keith’s “35 Biggest Hits” debuted at No. 2, followed by Madonna, Clay Aiken and Mariah Carey. Leona Lewis fell one spot to No. 6. The rest of the top 10 consisted of albums in their first week on the chart by, respectively, Gavin DeGraw, Josh Groban, Dierks Bentley, and Luis Miguel.

Barbara Walters’ relentlessness in hawking her new book, “Audition,” has paid off in the form of the top spot on the New York Times bestseller list. The only other new entrants on the non-fiction side are Carl Hiassen’s “The Downhill Lie” and “The Chris Farley Show,” a biography by the late comic’s brother. Stephanie Meyer and James Patterson are running 1-2 on the fiction list.

FOX, fashionably late to the upfronts this year, released their 2008-9 schedule yesterday.

Back are “Terminator: the Sarah Connor Chronicles” and “Prison Break” (as you predictied). “The Moment of Truth” returns as well. But apparently we’ve seen the last of “Back to You,” “Canterbury’s Law,” “K-Ville,” “New Amsterdam,” “The Return of Jezebel James,” and “Unhitched.”

FOX execs are hoping the new J.J. Abrams show “Fringe” – one of only two new shows set to debut in the fall – is more “Lost” than “Six Degrees.” Joss Whedon of “Buffy” fame offers “Dollhouse,” which will hit the small screen early in ’09.

Not long ago Media Predict users generated perfect forcasts for television cancellations for the fall season. Our users were perfect in the spring too, recording 100% accuracy in markets forecasting whether bubble shows would survive. See a full listing of television markets.  

Over at ABC, living to see another day are “Boston Legal,” “Eli Stone,” and “Dirty Sexy Money.” “Scrubs” will make the switch to ABC after NBC declined to renew it. New shows include “Life on Mars” (in the plush post-“Grey’s Anatomy” time slot) and “Opportunity Knocks,” a reality game show from Ashton Kutcher. Here is ABC’s complete fall schedule.

“Moonlight” got the axe from CBS (no thanks to “Jericho,” another show with a small but rabid fan base that underperformed after execs renewed it for a second season). There are already rumors that Mick St. John will find his way to the CW, however, so “Moonlight” fans shouldn’t despair just yet. Returning shows on CBS include “The New Adventures of Old Christine,” “How I Met Your Mother,” “The Big Bang Theory,” and “Two and a Half Men.” A minute-by-minute breakdown of the CBS presentation can be found here.

NBC allegedly attempted to kill the upfronts by announcing their fall schedule last month. In case you missed it then, check out this recap of NBC’s fall/winter schedule. Highlights include “Knight Rider” and a spin-off of “The Office.”

 FOX will announce their fall line-up tomorrow. Check back then to find out what shows will flank “American Idol.”

Robert Downey Jr. and “Iron Man” once again reigned supreme in its second week at the weekend box office, trouncing a dismal “Speed Racer” by more than $30 million. “Iron Man” took in $50.5 million after its opening weekend of $100.8 million. “Speed Racer” ($20.2 million) barely edged “What Happens in Vegas” ($20 million), with “Made of Honor” ($7.6 million) and “Baby Mama” ($5.8 million) filling out the top 5.

Madonna bumped Mariah from the No. 1 spot on the Billboard 200. Unfortunately for Madge, a German techno band called Scooter unseated her from the top of the UK charts. Leona Lewis drops to third, followed by chart newcomers Lyfe Jennings, Def Leppard, the Roots, Portishead, and Mudcrutch.

Nielsen ratings for the week of April 28 can be found here. When something other than “American Idol” or “Dancing With the Stars” occupies spots 1-4, we’ll let you know.

Ron Paul’s “The Revolution” finally hit the top spot on the NYT non-fiction list in its second week out, followed by the latest “memoir” from Augusten Burroughs. Also on the non-fiction list: Cokie Roberts, Jimmy Carter, Fareed Zakaria, and Sidney Poitier. Hard as it is to believe, James Patterson has a new book out, and it tops this week’s fiction list.

In case you haven’t heard (or didn’t see it this weekend) Robert Downey Jr. and Jon Favreau scored a monster hit with “Iron Man.” The first flick that Marvel has bankrolled far exceeded anyone’s expectations by pulling in a reported $104 million since its late Thursday debut. “Made of Honor” ($15.5 million), “Baby Mama” ($10.3 million), “Forgetting Sarah Marshall” ($6.1 million), and “Harold and Kumar…” ($6 million) rounded out the top 5.

Elsewhere, “American Idol” was the most watched show in America – two times over – for the umpteenth week in a row. “Dancing With the Stars” ran a close 3rd and 4th. “Grey’s Anatomy,” “CSI,” and “Desperate Housewives” all pulled in more than 17 million viewers apiece.

Mimi reigns supreme on the Billboard 200 once again. Leona Lewis holds firm at No. 2, followed by Flight of the Conchords, Ashlee Simpson with “Bittersweet World,” and Atmosphere with “When Life Gives You Lemons, You Paint That Shit Gold.”

Chelsea Handler, a noted triple threat, can add NYT No. 1 best-selling author to her resume with “Are You There, Vodka? It’s Me, Chelsea.” Despite frantic efforts by his supporters to get it to the top of the list, Ron Paul’s “The Revolution” hit the list only at No. 7. David Baldacci’s “The Whole Truth” shoots to the top of the NYT fiction list in its first week out, bumping Harlan Coben’s “Hold Tight” from the top spot. Iris Johansen, Stuart Woods and Amanda Quick also debuted in the top 15.

Tina Fey and Amy Poehler’s “Baby Mama” pulled in $18.3 million in its opening weekend at the box office, good for the top spot (in what’s sure to be the last sub-$20 million opening weekend for awhile). MP users turned in a near-perfect prediction for “Harold & Kumar Escape from Guantanamo,” which registered a $14.6 million debut. “Forbidden Kingdom” fell to third with $11.2 million, followed by “Forgetting Sarah Marshall” and “Nim’s Island.”

On the Billboard 200 the emancipation of Mimi continues, as Mariah Carey landed at No. 1. Leona Lewis, Miley Cyrus, and Lady Antebellum filled out the top five, while R.E.M. slid from fifth to ninth in only its third week out. Taylor Swift crept back in to the top 10 in her self-titled album’s 78th week on the charts.

It appears total domination of the network ratings just isn’t good enough for FOX. “American Idol” continues to crush the competition in the Nielsen ratings. Still, the network is performing online research to determine how the show might be improved.

Julie Andrews’ memoir “Home” is No. 2 on the NYT non-fiction list. It covers “from birth to being cast as Mary Poppins.” Fans of the book can expect a sequel in 2-3 years. Speaking of sequels, the 9th book in Alexander McCall Smith’s Ladies’ Detective Agency series enters the fiction list at #3.

Teen slasher remake “Prom Night” killed at the box office, pulling in nearly $23 million to top meager competition from Keanu Reaves in “Street Kings” ($12 million). Everything’s coming up aces for “21,” which added $11 million to its box office take for a total of $63 million through three weeks. “Smart People” opened back at 7th, with a little over $4 million.

George Strait’s “Troubadour” and R.E.M.’s “Accelerate” ran 1-2 on the Billboard 200. Van Morrison barely cracked the top 10 with “Keep it Simple,” while the soundtrack for “Alvin and the Chipmunks,” which came out four months ago, jumped back in to the top 5.

Yet again “American Idol” was the most watched show on television this week. Twice. “CSI” managed to unseat the “Dancing With the Stars” results show for 4th place in what was a strong week for CBS. But don’t break out the party favors just yet, Les Moonves: Goldman Sachs reiterated its sell rating on CBS. It seems the network has a little problem the analysts like to call “limited appreciation potential.”

Notable news from the New York Times bestseller lists: Julie Andrews is somehow still relevant, Kurt Vonnegut has a new book out despite being dead, and Jose Canseco is not only a two-time bestselling author but a quality individual.

If George Clooney really is the “last movie star,” as Time breathlessly asserted, Hollywood may be in trouble. Clooney’s “Leatherheads” limped to a second place finish in its opening weekend, behind Kevin Spacey and Co. in “21.” Kid flick “Nim’s Island” debuted in third with $13.3 million, “Horton Hears a Who” pulled in $9.1 million to bring its 4-week total to $131 million and change. “The Ruins” opened in fifth with $7.84 million.

DAY26’s self-titled album debuted at #1 on the Billboard 200, trailed by Panic at the Disco (now sans exclamation point), Counting Crows, and Danity Kane. The Raconteurs hit the charts at #7 with their hastily-released second album, “Consolers of the Lonely.” The surprise early-release strategy didn’t work out for Gnarls Barkley, which failed to crack the top 10 in either of its first two weeks.

Mariah Carey and Madonna, not exactly pals, were forced to share the spotlight last week in a delicious bit of irony. Mariah’s 18th No. 1 single, “Touch My Body,” pushed her past Elvis and within striking distance of the Beatles’ 20. “4 Minutes” became Madonna’s 37th top 10 single, also moving her past The King.

Good news for FOX competitors: “American Idol” didn’t take the top 3 spots in the Nielsen ratings for the first time in ages. The bad news: FOX only ran two episodes last week. “Dancing With the Stars” and its results show pulled in strong ratings to finish 3rd and 4th, respectively.

Jonathan Kellerman sits atop a slew of newcomers on the New York Times fiction list. On the non-fiction side of things, copies of “Brett Favre: The Tribute” are flying off the shelves. They’re expected to go up in value just as soon as Favre unretires.

Despite less-than-stellar reviews, the highest grossing movie over the weekend was “21,” based on Ben Mezrich’s book “Bringing Down the House.” The flick pulled in $23.7 million to displace “Horton Hears a Who,” which fell to second but became the first movie of 2008 to surpass the $100 million mark. “Superhero Movie” finished third with $9.5 million and “Tyler Perry’s Meet the Browns” limped to fourth with $7.8 million. “Leatherheads” and “The Ruins” open April 4, headlining another probable ho-hum weekend at the box office.

Flo Rida’s “Mail on Sunday” entered the Billboard 200 at #4. Girl group Danity Kane, of “Making the Band” fame, hit the charts at #1 with “Welcome to the Dollhouse.” Rick Ro$$, and Jack Johnson also remained in the top 5, alongside Various Artists 27th “Now” album.

“American Idol” A and B were the most-watched TV shows of the week, followed by “Dancing With the Stars” A and B and “Two and a Half Men.” “60 Minutes,” “Law & Order,” “The New Adventures of Old Christine,” “Lost,” and “Moment of Truth” rounded out the top 10.

David Sheff’s “Beautiful Boy,” a memoir about his son’s struggles with meth addiction, is the #1 book on the NYT non-fiction list. “Tell Me Where it Hurts” by Nick Trout is an entry in the increasingly underserved “animal book” market and hits the list at lucky #13.

Will your favorite television shows be renewed for next year? Amid the strike chaos, many freshman shows have already gotten the axe – or the reprieve. Casualties include the heavily-hyped “Bionic Woman.” Survivors include “Chuck,” “Life,” and “Pushing Daisies.”

But the fates of other shows are still up in the air – and we’ll let you make your predictions as to who will survive. Current markets include (among others) “Friday Night Lights,” “Terminator: Sarah Connor Chronicles,” “Kid Nation,” “Moonlight,” “Scrubs,” and – yes – “Cavemen.”

According to reports, fans are sending light bulbs to NBC executives to keep “Friday Night Lights” on the air. And apparently New York Magazine is asking fans to send in (no joke) locks of hair to keep “Cavemen” alive.

Will your favorite show survive? See our full listing of renewal markets, and watch for new markets in the coming weeks.
