Five films are opening wide this weekend but none is expected to unseat Superbad from the top of the box office. The Judd Apatow comedy is expected to gross about $18-22 million, according to analyst, while the Jet Li/Jason Stratham action movie War is likely to come in a close second with $16-20 million. The Nanny Diaries, starring Scarlett Johansson, is expected to vie for third place with Mr. Bean's Holiday, starring Rowan Atkinson. Each is expected to debut with about $7-10 million. Analysts say that the relatively low-budget Resurrecting the Champ, starring Josh Hartnett and Samuel L. Jackson, will not take in more than $5 million.
