9. The Bourne Identity (2002)
Damon proved he had the chops to go up against Tom Cruise as an action star in The Bourne Identity which spawned an entire series with four films to date. He retired from the series after the third film, while a fourth centering around a new character starring Jeremy Renner was released in 2012. While he claimed he would not return to the franchise, the success of it has lured him back for fifth film to be released in 2016.
