Colin's last name at birth was Dillingham, as it was his mother's maiden name, but it was later changed to Hanks after his parents married in January of 1978.
Colin(on keeping his last name): It's a total catch-22. The way I see it is maybe I've got more balls, you know, since I didn't change my name. I mean it was never a big thing for me. I paid it about two seconds worth of thought and then that was really sort of it. Ultimately it really doesn't matter. And also then I think it doesn't confuse people so much 'cause I remember going 'Wait a minute. You mean to tell me that Charlie Sheen and Emilio Estevez are brothers?' I didn't want to come up with some generic Johnny Bravo type name. I'm not that cool, so I might as well stick with my birth name.
