Chris Evans has become so well known for playing Captain America that the two are basically one and the same, making it difficult to imagine that the actor could possibly do anything particularly un-heroic. But it looks like that’s exactly what he’s going to do next: Evans is eyeing the lead role in Jekyll — or should we say lead roles, plural, since he’ll also be taking on the sinister persona of Mr. Hyde.

Deadline reports that Evans is in talks to star in Jekyll, Lionsgate’s big screen adaptation of the BBC One miniseries from Doctor Who and Sherlock showrunner Steven Moffat. The series originally aired in 2007, and centers on Tom Jackman, the last descendant of Dr. Jekyll and his nefarious alter ego, Mr. Hyde. A contemporary take on the classic Robert Louis Stevenson story, the series follows Jackman as he uses the latest technology to keep his dark half at bay.

It sounds like a complex role that will allow Evans to subvert and possibly even deconstruct the heroic persona firmly established by the MCU in a fascinating way. The Jekyll film has a screenplay by Charles Mondry and Anthony Bagarozzi, who previously scripted The Nice Guys for Shane Black, and are re-teaming with the director for Doc Savage.

But Jekyll isn’t the only film bringing the iconic doctor and his evil personality to the big screen — Russell Crowe is playing the Jekyll and Hyde role in Alex Kurtzman’s upcoming reboot of The Mummy, which stars Tom Cruise and is part of Universal’s new franchise of monster movies. The studio is reportedly considering giving Crowe his own standalone Jekyll and Hyde film, which should make for interesting competition with Evans’ project.
