Vin Diesel's Riddick topped the movie box office this weekend as the fall season got underway, grossing a solid $18.7 million in its first week of release.
The weekend after Labor Day is always sluggish in terms of moviegoing. Riddick helped drive revenue up 24 percent over the same weekend a year ago.
"Face it, this is never a great weekend. I was hoping Riddick would get to $20 million, but this is a great result," said Universal's distribution chief Nikki Rocco.
Riddick opens in 22 more international markets this weekend, including the U.K. and Hong Kong, where the three-quel is expected to perform well.
