Batman Begins is still #1 at the B.O. with Bewitched taking #2 and word of mouth expected to ward off newcomers. Box Office Guru has the story:

Bewitched essentially opened like a Kidman flick. The figure was just a bit weaker than the $21.4M bow of last June’s comedy The Stepford Wives as well as April’s political thriller The Interpreter which debuted to $22.8M. Things will get pretty rocky on Wednesday when Tom Cruise invades theaters with War of the Worlds which aims to bump movies starring his current fiancee Katie Holmes and his ex-wife Nicole Kidman down.
