Graham McTavish, who stars alongside Sylvestor Stallone in Rambo, has joined Christopher Lee and Joan Collins on the cast of LA-based Fantastic Films International and London-based CFC Film's horror film Cowboys For Christ.

Robin Hardy is set to begin filming on Apr 10 in Dumfries, Scotland, the same region where he directed Lee in the 1973 cult classic The Wicker Man. Since then hardy has made only one film, the 1986 thriller The Fantasist.

Cowboys For Christ is similar in tone to The Wicker Man as it follows the journey of two evangelical Christian virgins from Texas who arrive in Scotland to spread the Gospel. Lee plays an influential local man who shapes the hapless pair's fate.

Hardy wrote the screenplay and Paul Wesley and Susie Amy round out the key cast.
