(about Captain Tom Ryan, the character he played in "Primeval")
Mark: Ryan is just a soldier, but he's a very good one; he's ex-special forces and has been identified by some rather shadowy characters in the Government as someone who can get the job done in some pretty crazy situations. He's someone who does what he's told, when he's told and doesn't ask questions.
Mark: I always wanted to be an actor and I always wanted to be a soldier. I loved all those wonderful old films like A Bridge Too Far and so on and all those actors were in the Army for National Service or the War.
