UFC events don't count as movies.
I don't think that movie Fighting will be good at all. Not even as good as Never Back Down, because its not about MMA. Based on the commercial, it looks like standup underground street fighting. And also the plot sounds alot like that Van Damme movie Lionheart. On the other hand, Cung Le is in the movie and he's one my favorite Strikeforce fighters (next to Gina ofc)
