Clark Gregg
Fans of the Marvel Cinematic Universe are familiar with Gregg’s work. He has a prominent presence in the cinematic world, and given how many action sequences there are in these superhero films, it makes sense that he would require a stunt double.
It’s worth noting that Clark and his stunt double appear to be nearly identical. It’s very difficult to tell who Clark is and who the stunt actor is from this vantage point. Even their hairstyles are almost similar!
