The movie Virtuosity just ended. That's the flick where a pre-Training Day Denzel Washington plays a cop who has to take down a virtual reality program which is a composite of notorious serial killers ( played by Russell Crowe) that has escaped into the real world (don't ask).
I spied in the end credits "Special Vocal Effects by Frank Welker." Frank Welker, the voice of Freddie in Scooby Doo, the source of "Spock screams" in Star Trek III, and the voice of billions (okay, millions) of cartoon characters over the last 40+years.
Frank Welker: the John (he's been in every movie ever made) Carradine of voice over actors.
