Haha, yeah, we turned the velocity down on the guns so that it wouldn't hurt so much when we were shooting each other take after take. Unfortunately what we found out was one, the paint doesn't break when it's going slower and two, it hurts way more when the paint doesn't break, haha. Needless to say, we turned it back up about half way through the shoot.
Funny movie. Though a lot of your paint just bounces. - I bet you were having a blast.
