Whether you know who Stan Lee is or not, if you've watched any Marvel movies over the past decade you'll no doubt have spotted him in his short cameo roles, which are always fun to look out for.
Stan Lee, for the uninitiated, is the co-creator of many much-loved superheroes such as Spider-Man, the Hulk, the Fantastic Four, Iron Man, Thor, the X-Men, and more.
A new video released by Audi of America on Tuesday shows Mr Lee teaching the next generation of cameo actors his technique. His students include Kevin Smith (Clerks), Michael Rooker (Guardians of the Galaxy) , and Tara Reid (American Pie) .
The video was also directed by Kevin Smith and features cameos from Jason Mewes (Mallrats) and Lou Ferrigno (The Incredible Hulk). The Audi S8 is in there too, of course, as this is an advert for Audi and Marvel Studios' partnership, along with the new Avengers movie.
Avengers: Age of Ultron hits cinemas in the US on Friday this week, but you can already go and see it in the UK now.
