LOS ANGELES (AP) - A Warner Bros. executive says the Batman sequel "The Dark Knight" has set a single-day box office record by taking in $66.4 million on opening day.

The movie's Friday haul surpasses the previous record of $59.8 million set last year by "Spider-Man 3." ''The Dark Knight" also might break the opening weekend record of $151.1 million that also was posted by "Spider-Man 3."

Warner Bros. head of distribution Dan Fellman says the death of co-star Heath Ledger and the buzz about his frenzied performance as the Batman villain Joker was a big part of the movie's allure.
