Two big openings over the weekend – “Charlie and the Chocolate Factory” started out with $55.4 million and “Wedding Crashers” bowed with $32.2 million – kept the marketplace healthy for the second week in a row. Warner Bros. opened “Charlie” in 3,770 theaters while New Line bowed “Crashers” at 2,925. The remake of the 1971 kidpic drew the biggest opening for star Johnny Depp, surpassing the bow for 2003’s “Pirates of the Caribbean: The Curse of the Black Pearl.” The opening for “Charlie” is also the best for a PG-rated pic in July. Meanwhile, “Crashers” performed well for an R-rated movie. The last R film to open bigger than the Vince Vaughn-Owen Wilson comedy was last summer’s “Troy.” Facing stiff competition from the weekend’s new pics, last week’s champ, 20th Century Fox’s “Fantastic Four,” tumbled 59% in its sophomore session, grossing $22.7 million over the frame. Still, the total for the comicbook movie is now $100.1 million. Behind it in the No. 4 spot was Paramount and DreamWorks’ “War of the Worlds” with $15 million, bringing the total on the Steven Spielberg-Tom Cruise alien invasion film to $192.2 million. Warners’ “Batman Begins” rounded out the top five with $5.6 million in its fifth weekend. The movie has made $182.7 million so far in its domestic run.
