Riddick Debuts in First Place at the Box Office

Vin Diesel muscled his way to the top of the domestic box office this weekend with Riddick, which debuted with an estimated $18.7 million -- a softer than predicted opening for the sci-fi threequel that pre-release tracking suggested would bow north of $20 million.

The second film, The Chronicles of Riddick, opened to $24 million back in summer 2004, but that sequel also cost $105 million and grossed only a disappointing $115.8 million worldwide.

Here are the weekend estimates via Rentrak:

1. Riddick $18.7 million

2. Lee Daniels' The Butler $8.9 million

3. Instructions Not Included $8.1 million

4. We're the Millers $7.9 million

5. Planes $4.3 million

6. One Direction: This Is Us $4.1 million

7. Elysium $3.1 million

8. Blue Jasmine $2.7 million

9. Percy Jackson: Sea of Monsters $2.5 million

10. The World's End $2.3 million
