Fair warning, this is very clearly an ad for Audi and Avengers: Age of Ultron, but it’s pretty priceless. Stan Lee has been rocking the cameo since Marvel movies began and now he’s teaching his craft to others. Usually these things aren’t so well done, but the meta-ness of cramming cameos into a short about cameos delivers. Probably because the whole thing was directed by Kevin Smith.
The only real question is why Michael Rooker is there. Does anyone think of him as a cameo guy?
