Mad Men star says he's "been in contention for quite a few" superhero roles, but he's confident he made the "right decision" in turning them all down.

"The deals that they make you do are so draconian," he told RadioTimes. "And, of course, you are signed on for not only the movie ... but at least two more that you haven't read, and you have no idea what they are going to be and all the crossover ones you are going to have to do."

"For me to sign on now to do a superhero movie would mean I would be working until I am 50 as that particular superhero," he continued. "It's a lot of work at one thing, which is not necessarily the reason I got into the business, which is to do many things. If you want to spend all day pressing the same key, that ... seems an odd choice."

Hamm was one of the dozens of actors rumored to be up for the role of Doctor Strange, a part that ultimately went to Benedict Cumberbatch. Before that, he had to fend off rumors of him playing Superman.

His desire to do something different at this stage in his career makes sense, considering he's spent the past seven years playing Don Draper on AMC's soon-to-conclude drama series Mad Men. Hamm can next be seen in the upcoming holiday episode of the U.K. anthology series Black Mirror, titled Black Mirror: White Christmas.
