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.
