Comin' at Ya!

I was born in 1977, and this movie was my first experience with 3d. I went with my brother (3 years older) and my dad. My dad was reading the paper and saw 3d, and he just had to take his two young sons. I was only 11 or 12, but I remember the theater guy trying to talk my dad out of it, because I think it was R, or maybe just the violence. I remember thinking it was cool, but really now only remember a scene where a topless old time prostitute shakes her boobs at the screen. And no, my dad didn't take away our glasses when that scene appeared, although I thought for sure that he would. I was reading the other comments, and know I vaguely remember arrows being shot at us and one scene where multiple knives where thrown. Man, am I glad for the internet, I have been trying to find this title for years. Maybe one day Ill take my kids.
