In 1986, he directed his first film that did not involve Henson, "Little Shop Of Horrors". The musical film starred Rick Moranis and Ellen Greene, as well as Vincent Gardenia, Steve Martin, Bill Murray, John Candy, Christopher Guest, Jim Belushi and a 15-foot-tall talking plant (voiced by Levi Stubbs) which at times required up to 40 puppeteers to operate. The film allowed Oz to show his ability to work with live actors and led to opportunities to direct films that did not include puppetry.
