Felix Silla was born in Italy and trained as a circus performer. In the United States, he toured with the Ringling Bros. and Barnum & Bailey Show. His multiple talents - as a bareback rider, trapeze artist and tumbler - brought him to Hollywood where he first became a stuntman. His best-known roles are Twiki in Buck Rogers in the 25th Century, Cousin Itt on the long-running TV series, The Addams Family, and Ewok in Star Wars Episode VI: The Return of the Jedi. He had doubled--often for children--in such hits as The Towering Inferno (1974), The Hindenburg (1975) and Battlestar Galactica (1978).
