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.
