"Captain America: Civil War" might have a Hulk.

During an interview with BBC Radio 1, Anthony Mackie -- who plays Falcon in "Civil War" -- namedropped Mark Ruffalo as he praised the film. Ruffalo has not yet been confirmed for the film, but Mackie includes his name in discussing "Civil War's" roster of "really good" actors.

"Captain America: Civil War" Will Focus on Steve Rogers & His Struggle, Says Chris Evans

"Having seen the movie, it's Marvel's best movie thus far," Mackie says at the 17:25 mark. "And I'm being honest -- if a Marvel movie sucks, a movie in the Marvel universe, I'll tell you it sucked... 'Winter Soldier' and 'Iron Man 1' are probably Marvel's two best movies. I feel like ['Civil War'] beats both of those movies. It's really, really good. Because it's more of an acting movie than an action movie, I feel like the story is very concise and interesting, and you get to see Robert Downey Jr and Chris Evans and Scarlett Johannson and Mark Ruffalo and everybody just do really, really good acting. And then there's action in it. The great thing about being in a Marvel movie? They have really good actors. I mean, Don Cheadle is in the Marvel Universe!

"I think it might be the first superhero movie that might be up for Best Picture," he added.

Though Ruffalo has not been directly connected "Civil War" before this point, he will reprise his role as Bruce Banner/the Hulk in "Thor: Ragnarok," the next installment in the Marvel Cinematic Universe. Additionally, it's worth taking Mackie's comments with a grain of salt, as he also comments on the MCU at large during his discussion of the film.

Directed by Joe and Anthony Russo and starring Chris Evans, Robert Downey Jr., Scarlett Johansson, Anthony Mackie, Sebastian Stan and more, "Captain America: Civil War" opens on May 6, 2016.
