There was this film my brother and I watched long ago and he can't remember it so I'll try asking here =)

All I remember is there are 2 brothers, twins, one is good and the other evil, the good one is like a gnome and the other like a small troll. I think it was a 15 rated film maybe 18. I think the good brother shoots the other one at the end, it's a really weird fantasy cartoon. I wish I could describe it in more detail.

If anyone knows it would really help =)

Thanks for your time

Possibly Wizards (1977) (http://www.imdb.com/title/tt0076929/)
