Channing Tatum, This is the End
This entire movie is based on cameos. This is the End shows the end of the world as seen from the perspective of a bunch of real-life Hollywood friends like Seth Rogen and Dave Franco. However, in the very end, there's an appearance from Channing Tatum, who, like everyone else, plays himself. Only his role is that he's Danny McBride's post-apocalyptic sex slave.
