LOS ANGELES (AP) -- A Warner Bros. executive says the Batman sequel "The Dark Knight" has taken in $155.34 million to top "Spider-Man 3" for best opening weekend ever at the box office.

The figures released Sunday show "The Dark Knight" more than $4 million ahead of the $151.1 million first weekend for "Spider-Man 3" in May 2007.

Studio distribution chief Dan Fellman says "The Dark Knight" also broke the "Spider-Man 3" record for best debut in IMAX large-screen theaters with $6.2 million. "Spider-Man 3" opened with $4.7 million in IMAX cinemas.
