"The Dark Knight" lit up cash registers during its midnight debut, stealing away with a record $18.5 million from 3,040 theaters, distributor Warner Bros. said Friday.

That bested the 2005 performance of "Star Wars Episode III: The Revenge of the Sith," which took in $16.9 million during its midnight debut in 2,915 venues.

"The Dark Knight" figure did not include any of its 3 a.m. or 6 a.m. showings.

And while Batman only strikes at night, all indications are that "The Dark Knight" will keep landing blows: Advance ticket sales were booming.

The early numbers mean "The Dark Knight" will likely join the ranks of 10 other films that debuted on non-holiday weekends and cleared more than $100 million from Friday to Sunday, said Paul Dergarabedian, president of tracking firm Media By Numbers
