Something awesome I learned today: when some kid asked the Make A Wish Foundation to meet Hellboy, Ron Perlman himself made the appearance in character and in full movie makeup. Some actors are good at what they do, and some, it turns out, are also wonderful people. Well done, Perlman.

PS - He spent 4 hours in makeup for a that meeting.
PPS - And probably just as long to get out of costume afterwards, too.
