No surprise that Sex and the City: The Movie was tops at the box office this weekend - but few could have predicted that the film's estimated $55.7 million would make it the best opening ever for an R-rated comedy.

1. Sex and the City: The Movie: $55.7 million
2. Indiana Jones and the Kingdom of the Crystal Skull: $46 million
3. The Strangers: $20.7 million
