During a recent panel at Fan Expo Canada, Smith confirmed that he's certainly open to joining the MCU - if the perfect role comes along.
"I’d love to. They’ve got ask me though, the swines." Smith joked. "But it would have to be the right project."
So what would make a part in the MCU right for Smith? Taking a cue from his former Doctor Who co-star, Karen Gillan, it would have to be a role that defies people's perceptions of him.
"It would have to be something that felt different enough to Doctor Who. I love so many of those movies and I love Nebula, because Karen’s blue. With no hair. Anyway, I’d love to… If you’re listening, Marvel.”
The crossover of Doctor Who actors in the MCU has only grown over the years. Previous Doctors Christopher Eccleston and David Tennant went on to take MCU roles, as Thor: The Dark World's Malekith and Jessica Jones' Kilgrave. Even Smith's companion, Jenna Coleman, had a small cameo in Captain America: The First Avenger.
This isn't the first time that Smith's name has been tied to the world of superhero adaptations. The actor campaigned to play The Riddler in a DCEU film back in 2014. He also was rumored to be up for a mystery role in Sony' Venom film, but Riz Ahmed is in talks to get the part.
The Doctor Who Christmas Special will air on Christmas Day, Dec. 25, 2017.
