Iron Man 2 opens in America Friday at 12:01 am, and when it opens, it’ll play in more theaters than any other movie in history. The movie will roll out into a record-setting 4,380 locations. The previous booking record was held by The Dark Knight which played in 4,366 theaters.

Some have speculated that Iron Man 2 might be capable of beating Dark Knight’s opening weekend box office record, pushing it out into such a wide theatrical release is sure to help. Though the film’s receiving somewhat mixed reaction from exiting audiences, that won’t really hurt it until after the big weekend numbers are already in. That’s the sort of thing that only really hurts repeat viewings. If Iron Man 2 fills those theaters up, TDK’s opening weekend record could be in trouble. Current predictions put Iron Man 2’s opening take at between $155 and $160 million. Dark Knight’s record stands strong at $158.4 million.
