That`s the responsibility of all actors: to keep your character as vibrant as possible. I just live my life and I like my characters to live that life, too. At least Scotty, anyway, because Scotty is the closest to Jimmy Doohan that I`ve ever done.
I really didn`t have to work, shall we say, with "Star Trek." It was a natural. When I opened my mouth, there was Scotty. It`s like I tell people what you see in Scotty is 99% James Doohan and 1% accent.
What shocked me, my manager called me up one day and told me that I was going to do a video on "Cold Fusion: Fire from Water" and I couldn`t believe it. I couldn`t wait to get there and start working on it.
Well, I was always... I used to get 100% in physics and chemistry and mathematics (well, maybe a couple of points off in mathematics), and that was in high school.
