18 Actors You Totally Forgot Were In Marvel Movies

12. Olivia Munn - Iron Man 2

Iron Man 2 might be one of the worst movies in the MCU to date, but it did at least bring in some interesting ideas. Sam Rockwell's Justin Hammer was great, for instance, and the exploration of Tony Stark's addictions and self-destructive patterns of behaviour were a huge part of his character development.

Unfortunately, thanks to a poor script, over-zealous editing and some straight-up iffy moments, most of that is too easily forgotten. And so too is the brief cameo by Olivia Munn, who turns up playing reporter Chess Roberts at the Stark Expo.

In 2010, when the film came out, she was mostly unknown, aside from some TV work and lesser parts in movies - she wouldn't really catch her break in The Newsroom until 2012, and that meant such small parts in the MCU were possible. Looking back, it's like an odd little before-she-was-famous capsule.
