Now, I've never seen a Scott Adkins film but I have seen a few of his martial artist (mostly pinched from Tae Kwon Do) videos on YouTube and he's definitely got talent in that area. He looks a bit like the little brother of Jason's Anthem.
Only seen one Craig Fairbrass film Gerard Johnson's very good Muscle which most of his fans didn't like. He was damn good in that but I've never been tempted by all those Poundland titles.
This film seems to have 5 or 6 different releases in Germany.
