4. Christopher Walken In Ripper
Technically, I could put everyone from Ripper in here, as the game is overflowing with odd cameos from people like Jimmy Walker and Paul Giammati. 90s adventure games loved using celebrities. After all, full motion video is the future. None of that partial motion video for us. We're like movies, only better because you have to hit a button before the movie. Christopher Walken, who is rivaled only by Nicolas Cage for his inability to turn down acting roles, chews so much scenery as the shady cop that he has to install a second mouth on his forehead just so he can chew to his satisfaction. Its historically known as one of his most subtle performances.
