James Marsden got his start in Hollywood in the early 1990s, scoring guest appearances on shows like Party of Five and Saved by the Bell: The New Class, as well as a regular role on the fifth season of Ally McBeal. But Marsden's real big break came in 2000, when he was cast as Scott Summers, also known as Cyclops, in director Bryan Singer's X-Men. Unfortunately for Marsden, Cyclops, an important character in the comics, ended up with a diminished role in the films as the franchise continued. However, that did free Marsden up to work on other projects with Singer — including 2006's Superman Returns, in which he played Richard White, Lois Lane's (Kate Bosworth) fiancé.

After a reduced role in 2006's X-Men: The Last Stand (thanks in part to his Superman Returns gig), Marsden did make a return to the franchise for 2014's X-Men: Days of Future Past. He reappeared alongside other former cast members like Famke Janssen and Anna Paquin, who played Jean Grey and Rogue, respectively, in the first film.
