Joker has not only become the most profitable comic book movie of all time but it's led to many discussions, story-wise, about what's real and what's not with regards to Arthur Fleck's unreliable narrator status. A centerpiece of this is Zazie Beetz's neighbor character, Sophie, who was crucial to one of the twists in the plot, and whose ultimate fate was left unanswered

Beetz is also know for playing a big role in another comic book movie, as she was Deadpool 2's super-powered luck machine Domino. Of course, Deadpool is (the R-rated) part of Fox's X-Men universe, but now that Disney's brought the X-Men film rights back to Marvel, and Marvel plans on making an X-Men movie at some point, Beetz has gone on record saying she'd love to play Storm.Talking to ScreenGreek , Beetz was asked if she'd like another shot at Storm (since the actress previously auditioned for the role in 2016's X-Men: Apocalypse). "Yeah, I think I would be down," Beetz said."I guess obviously it depends on the script and it depends on if I think it’s a good script," she added. "I think it would be super fun to do that. Storm also essentially is such an iconic character. I mean it would be kind of big shoes to fill, I think.""I wouldn’t want to confuse audiences too much and be all over the place," she continued, "and now I’m doing DC as well. I think it would be super fun. I think it would be a dope opportunity.”Obviously, there's still a chance that the Deadpool series could mingle over into the MCU , somehow, so that would mean Beetz, hypothetically, would be playing two MCU characters. Of course, Gemma Chan's already doing that , by playing two different roles in Captain Marvel and Eternals, so it's not unheard of.Interested in lingering fan theories about Joker?
