18 Actors You Totally Forgot Were In Marvel Movies

7. Kate Mara - Iron Man 2

Before she landed the career-making role in House Of Cards, Kate Mara's profile was beginning to rise thanks to the likes of American Horror Story. But by 2010, she was still mostly unknown, despite some eye-catching performances.

All of that would change not so long later when she rose to leading actor status enough to be hired for the ill-fated Fantastic Four reboot, but that wasn't her first foray into Marvel movie-making.

In 2010, she appeared in Iron Man 2 as a US Marshall not even significant enough to get a name, despite some rumours suggesting she was going to be playing Bethany Cable.
