I just found out about this movie released last year. I couldn't find a topic about it so I thought I'd give a heads up. The Serbian name is Sveti Georgije ubiva azdahu and the full movie is on youtube with english subs (I won't post a link as it might break forum rules). I haven't watched it yet so I'm not sure if it's any good, but from a fan trailer on youtube it seems like it might have one or two good battle scenes:
Trailer - I've posted it from work so I don't know how good the sound i or whether its one of those youtube fanvids with music from another film. Also its a long trailer so it might well contain spoilers.
