IESB.net is reporting that Christian has signed on to a project called The Prisoners, which will potentially include Mark Wahlberg as co-star and Bryan Singer as director. Here's the basic plot:
After his 6-year-old daughter and her friend are kidnapped, a small-town carpenter butts heads with a young, brash detective in charge of the investigation. The father is a Bible-reading, deer-hunting survivalist. The cop, meanwhile, can’t wait to get to the city. Feeling failed by the law, the father captures the man he believes responsible and begins to torture him in a desperate attempt to find out what he did with the girls, whom he’s convinced are still alive.
They do stress that none of this is confirmed, so stay tuned. It does sound like just the sort of project Christian would be wonderful in, though!
