13 People You Didn't Know Were In The Marvel Cinematic Universe

5. Seth Green

Seth Green is perhaps known for being a 'celebrity nerd' as much as he is for his acting career, which has consisted of three Austin Powers films and the voice role of Chris Griffin in Family Guy. Green also has his own show on Cartoon Network's Adult Swim block. This production, Robot Chicken, showcases his love of subjects such as comics, sci-fi and video games through stop-motion sketches. This has been particularly exemplified by the show's specials, three of which have exclusively focused on Star Wars and two of which have focused on DC Comics. Not one for preferring a particular brand, however, Green has popped up twice in the Marvel Cinematic Universe. First he had an uncredited role as an expo attendee in Iron Man 2, before showing up in the hilarious post-credits scene in Guardians of the Galaxy. Here he voices Howard The Duck, a comic character that has become something of a joke due to the poor reception of his solo film outing in the eighties.
