Felix Silla was extremely versatile. Because of his small size (he was only 3'11"), he was often called upon to be the stunt double for children. He played a variety of roles through the years, from a "leprechaun" on Bonanza to a goblin on Bewitched to one of the Ewoks in Return of the Jedi. As Cousin Itt and Twiki he got to play recurring roles. And he played only the body in many of his roles, he was entirely wonderful when he actually got to speak in a part. A perfect example of this is his role as Litvak in The Black Bird. Felix Silla was perfect as the half-crazed villain. For younger Baby Boomers and Gen Xers, Felix Silla generated many fond memories.
