10 MORE Actors Who Played Multiple Roles In The MCU

10. Jon Favreau

For many years, Harold "Happy" Hogan has served as Tony Stark's personal bodyguard and chauffeur. He's not particularly good at the whole 'bodyguard' thing but Stark keeps him around since they've been friends for years.

It's common knowledge that the actor portraying Happy, Jon Favreau, was the director of Iron Man. Since the Emmy-nominated filmmaker is responsible for kicking off the entire Marvel Cinematic Universe, fans are eternally grateful to Favreau for bringing so many of our favourite comic characters to life.

However, few people realise that the New York director also played the most important character in the entire MCU - Iron Man! Even though it's impossible to see anyone portraying the Armoured Avenger apart from Robert Downey Jr, the director performed the motion-capture for him in the first two Iron Man films. Being the director, Favreau knew exactly how he wanted the wise-cracking superhero to move in certain shots and so, performed the motions himself when Downey Jr wasn't available.

Even though Jon Favreau will always be seen as Happy Hogan, no one can take away thee fact that he has technically portrayed a superhero.
