Some are pretty open about it, and there are those may not be for a number of personal or professional reasons. Tom Selleck, Clint Eastwood, and Charleston Heston are no-brainers, but Whoopi does surprise me. One other was Johnny Depp. I'm surprised that there aren't more "action" types that are pro 2a. I've seen R Lee and Joe Montenga on their respective shows - Lock N Load, Gun Stories, as well as Tim Nugent. Pen and Teller are as well, I'm sad I didn't get to catch their act at Shot.
