fe07-drewcarey-1004n (14k image)The Drew Carey’s Green Screen Show stars Carey and many of his quick-witted chums from his Whose Line is it Anyway? series and his tour group, including Brad Sherwood, Colin Mochrie, Greg Proops, Julie Larson and Sean Masterson. The cast performs improvisational skits suggested by a live audience, minus all props but in front of a so-called green screen, which is typically used by Hollywood as a canvas for computer-generated imagery that is added later. On Carey’s new show, the green screen is electronically replaced with background, costumes and assorted props that fit the skit — all created by a variety of animation techniques, including hand-drawn, stop-motion and computer-generated.
