Risky Business Blog is reporting that Christian Bale has attached himself to star in the upcoming Bryan Singer directed thriller Prisoners. Mark Wahlberg is also signed on to star in the film.

The script was written by Aaron Guzikowski, and focuses on the kidnapping of a six-year old and her best friend. The child's small-town father butts heads with the young, brash detective that is assigned to the case. At this time, Singer is not officially signed on to the picture. And Risky Business Blog claims that containing Bale and Wahlberg will be tough until they've nailed a set contract with all three involved.

The film does not have a set start date at this time.
