I just saw an interview with Mackie in which he mentions the Falcon:
You're also about to make history because of your recent casting in the new "Captain America" film. Tell us about it.
I'm playing the Falcon. He's this guy in Harlem who moved to California and became a drug dealer. His plane crashed, and he was genetically altered, and he can fly, has telepathic powers. He's the first African-American superhero. It makes me feel all the work I've done has been paying off. I have a son, nephews and nieces, and I love the idea that they can dress up as the Falcon on Halloween. They now have someone they can idolize. That's a huge honor for me.
