Lena Headey and Doreena Moore
It may be hard to see Lena Headey as anyone other than the nasty Cersei Lannister from The Game of Thrones. But she once played a major role in Terminator: The Sarah Connor Chronicles which was a TV adaptation of the box office smash hit Terminator that debuted back in 1984. Heady played the lead role as Sarah Connor in the show and as we all know, Connor was sort of a badass so that meant Headey had to be one too. However, more times than not, it was her stunt double, Doreena Moore that did all the hard stuff.
Mark Ruffalo and Anthony Molinari
Mark Ruffalo is a talented actor that seems to be able to play a wide variety of roles. We know he can do action based on his performance as the Hulk. However, he can do suspense too as we saw in Now You See Me 1 & 2. During the filming of that movie, Ruffalo enlisted the help of a stunt double that genuinely looked like he could be his twin brother. His name is Anthony Molinari, and as you can see here, he looks almost identical to Ruffalo and could literally pass as his twin brother. Not a bad gig if you think about it, because not only does it give him a job, but I’m sure it does wonders with the ladies.
