Warner Bros. had hoped its comic book-based Green Lantern would finish the weekend above $55 million, but the movie fell short of producers' expectations, with box-office results dropping drastically on Saturday. Though the film finished the week at $52.7 million, Warner Bros. is still optimistic that it will do well overseas and as kids get out of school for summer. The family-geared Mr. Popper's Penguins, starring Jim Carrey, also disappointed producers, finishing the weekend in third place at $18 million. In comparison to some of Carrey's earlier films, the results of Mr. Popper's Penguins is a sign that his career might be waning. Meanwhile, Woody Allen's Midnight in Paris is doing well both domestically and internationally—and is expected to be the director's biggest hit in more than 20 years.
