What Happens in Vegas came up trumps, debuting in third place with $20m. The romantic comedy starring Cameron Diaz and Ashton Kutcher performed well, finishing just behind Speed Racer despite its considerably smaller budget of $35m. It also boasted a better screen average than Speed Racer with $6,220 at 3,215 sites compared with $5,604 at 3,606 screens. Though both were well down on Iron Man's average of $12,284 at 4,111 theaters.
Made of Honor had a dignified 49% drop from last week's debut. Slipping to fourth spot, the romantic comedy's $7.6m gave it a total $26.3m. Baby Mama added $5.8m to take its three-week tally to $40.4m while Forgetting Sarah Marshall reached $50.8m after its fourth weekend total of $3.8m. Redbelt whipped up $1.1m to round out the top ten. The David Mamet martial arts drama starring Tim Allen moved up from 41st spot last week for a two-week total of $1.2m. Overall the box office was up 16% on the corresponding period last year when Spider-Man 3 remained atop the box office for a second week running with $58.2m.
Next week Iron Man is liable to lose his grip on top spot with the release of The Chronicles of Narnia: Prince Caspian. The question is whether the second in the Narnia series will top the $65.6m debut of 2005's The Lion, The Witch and the Wardrobe.
