Co-starring roles soon followed in the feature films Halloween 5: The Revenge of Michael Myers and Child's Play 3, which established Walker in the famed slasher movie sequel genre.
In Hollywood as a young actor, Walker worked with such notable actors as Kate Hudson, Melanie Griffith, John Goodman, Lea Thompson, Andy Dick, Tony Danza, Martin Mull, Haysha Deitsch, Donald Pleasence, Willford Brimley, John Ritter, and George C. Scott, and such directors as Tobe Hooper, James Burrows, and Garry Marshall.
In 1995, Walker was cast as a series regular in the Fox sitcom The Preston Episodes with David Alan Grier, and as the star of a CBS pilot called Shock Treatment.
Traveling across the country on the circus train, Walker performed in venues including The Cotton Bowl at the Texas State Fair, The United Center in Chicago and The L.A. Sports Arena.
Having studied previously with Second City Improvisation, the San Francisco Mime Troupe, and renowned clown Bill Irwin, Walker assembled a multi-talented group of actors, musicians, writers and acrobats, and the Troubadour Theater Company was born.
