Premise: ``Drew Carey's Green Screen Show'' is essentially ``Whose Line Is It Anyway?'' taken to the next level. Drew Carey and his merry band of improvisers are back on television, this time playing out their theater games in front of a green screen. Animators then take the skits and fill in backgrounds, props and whatever else they feel like throwing into the mix to animate the scenes that Carey and company come up with during the show. Four or five games, including Fill in the Blank and Freeze Tag, are usually played in each episode.
