Does Matt Bennett, who plays Robbie Shapiro on the Nickelodeon sitcom Victorious, really do the voice for his puppet Rex?
—Brian McCreary, Upper Sandusky, Ohio
Wisecracking dummy Rex is voiced by writer-actor Jake Farrow, 32, but Farrow's role is uncredited to help enhance the idea that Rex thinks and talks for itself. Bennett, 19, has taken ventriloquism lessons, and his coach, Jay Johnson, 62, was influential in the creation of Rex's character. Johnson played Chuck Campbell in the 1977-1981 sitcom Soap, where he had a puppet named Bob. "I'm glad to say I had him in my corner from the very beginning," Bennett says of his mentor. The teen star provides the voice of Louis, an otter, in next summer's movie Ice Age: Continental Drift.
