The Avengers: Age of Ultron has a jam-packed superhero cast, but there is one soaring member of Earth's Mightiest Heroes that may not make the cut.

Who Is Hulk Really Fighting In Johannesburg During 'Avengers 2'?

The Falcon is set to make his debut in April's Captain America: The Winter Soldier, but Samuel Wilson (Anthony Mackie) and his wings may be grounded for the rest of Phase Two. Although The Falocon sometimes flies with the Avengers, Mackie says he probably won't be teaming up with Captain America (Chris Evans) and Co. in the fight against Ultron.

"Chris [Evans] is a good friend of mine. [Avengers] starts in three weeks [and] I know he's read the script," Mackie told MovieWeb. "He's like, 'Yo, man, I read the Avengers script. It's good.' I was like, 'Really?' He said, 'Yeah, Joss [Whedon] is doing rewrites, but it's good. I was like, 'Great! So ... am I in it?' And he says, 'I've got to go. I'll be back.' What do you mean? Why can't you just tell me if I'm in the movie? No one will tell me, not one person, so I gave up on it."

The Avengers: Age of Ultron will hit theaters on May 1, 2015.
