8. Jesse Heiman - That Nerd Guy In Everything
The Role: Jesse Heiman is listed on several YouTube videos as "the greatest movie extra of all time", having appeared in a variety of films and TV shows (American Pie 2, Spider-Man, The Social Network, Glee) playing a nerdy extra hanging around in the background.
Why It's Amazing: Despite edging towards his forties, Heiman can still get away with playing young nerds, and the sheer proliferation of his output, working with directors like Martin Scorsese and David Fincher, is undeniably impressive.
What Happened?: Heiman did eventually achieve fame by appearing in a GoDaddy commercial where he is french kissed by model Bar Rafaeli, and he has also appeared on Jay Leno's Tonight Show. Meanwhile, his extensive extra work continues, playing in James Franco's directorial debut, As I Lay Dying this year.
