Although “Star Wars: Episode III — Revenge of the Sith” looks unlikely to take its place as the highest-grossing “Star Wars” overseas, as some predicted it would, the movie’s performance still holds up in a summer when studio tentpoles keep falling down. Just three movies, apart from “Sith,” have topped the $200 million mark this year, as opposed to seven by this time in 2004. But even with foreigners holding tightly to their wallets in what were once thought of as reliable territories (Germany, the U.K.), “Sith” handily outpaced its predecessor, “Attack of the Clones,” even before opening in its final territory, Japan, last weekend. And all of this includes Italy, where “Sith” B.O. lagged behind “Star Wars: Episode I — The Phantom Menace’s” take by over $1 million. “Sith” now sits 17th on the all-time worldwide list, with $782 million, with more than half its take coming from foreign coffers.
