Iron Man was the character who started it all when it came to the Marvel Cinematic Universe, and that is likely to make anybody picking up that mantle, even in a totally different way, think twice. Robert Downey Jr.’s performance as Tony Stark/Iron Man has become absolutely iconic, which is probably why John Stamos, who recently met up with Iron Man at Disneyland, wanted to do something similar for his own performance, until the directors told him he didn’t need to.

John Stamos will voice Iron Man in new episodes of the children's TV show "Spidey and his Amazing Friends." Stamos told ScreenRant that he came in thinking he’d play the character similar to Downey, because there are some similarities between the cartoon Iron Man’s relationship to Spider-Man in the series and the relationship Robert Downey Jr. and Tom Holland portrayed in the Marvel Cinematic Universe, but he ended up finding his own way to play the part.
