from boxofficeguru.com: Legions of George Lucas fans lined up and drove the much-anticipated Star Wars Episode III: Revenge of the Sith to the top of the North American charts shattering all kinds of box office records in the process and giving the film industry the jolt that was sorely needed. The final installment in the six-part sci-fi epic grossed a record $158.4M, according to final studio figures, over its four-day Thursday-to-Sunday opening weekend domestically and set a new global milestone debuting with a towering $303M worldwide since its Wednesday launch in certain territories.
It was the largest four-day opening ever eclipsing the $134.3M of The Matrix Reloaded from two years ago this month and also soared higher than the $110.2M of Episode II from 2002. Episode III grossed a stunning $108.4M over the traditional Friday-to-Sunday portion of the frame while playing in 3,661 theaters for a scorching $29,619 per-theater average. It ranks as the second largest Fri-to-Sun performance ever behind the $114.8M of Spider-Man in 2002 which launched on a Friday rather than a Thursday like Sith.
