There have been no shortage of casting rumors when it comes to Marvel Studios' next big project, the Phase Three adventure Doctor Strange, which already has Scott Derrickson attached to direct from a script by Jon Spaihts. Actors such as Johnny Depp, Benedict Cumberbatch, Jared Leto, Tom Hardy, Joaquin Phoenix and, most recently, Jon Hamm have been mentioned as possible candidates over the past year. But the role has still not been officially cast yet. Today, This Is Infamous reports that Boardwalk Empire star Jack Huston is the latest candidate.

The site's sources reveal the actor is "definitely in the running," although it isn't known if any of the previously-mentioned actors are still in contention as well. Jack Huston was previously one of the finalists for the Star-Lord role in Marvel's Guardians of the Galaxy, which was eventually won by Chris Pratt.

The actor also falls in line with the type of performer they typically cast as the lead in one of their new projects. At 31 years of age, he's young enough to allow him to stick around in the Marvel Cinematic Unvierse for several years, since actors typically sign multiple-picture deals with the studio. He also fits the right type of actor who is well-known but isn't quite a huge star yet, which fits with Marvel's approach to finding new stars on the rise instead of established actors who command higher salaries.

Insider's claim that Marvel is reportedly "very close to settling on a guy" for Doctor Strange, so perhaps we may get official confirmation on who is playing Steven Vincent Strange in the very near future.

Best known for playing Richard Harrow on HBO's Boardwalk Empire, Jack Huston recently starred in Kill Your Darlings and American Hustle on the big screen. We also reported earlier this month that he signed on to star in Paramount's Pride and Prejudice and Zombies.
