I really didn’t have to work, shall we say, with “Star Trek.” It was 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.

SPOCK: Spock, Captain. I trust all has gone well.
MCCOY: Spock, are you alive?
SPOCK: An illogical question, Doctor, since obviously you are hearing my voice.
MCCOY: Well, I don’t know why I was worried. You can’t kill a computer.
