Anthony Mackie has spent more than a decade inside the Marvel Cinematic Universe machine, so you might assume it takes quite a bit to leave him starstruck these days. Then Sir Ian McKellen and Sir Patrick Stewart walked onto the set of the upcoming Avengers: Doomsday, and suddenly the current Captain America was just another fan trying to work up the nerve to say hello.
Mackie recalled meeting the two X-Men legends while speaking with IMDb, and his story about introducing himself to the returning mutant actors is ridiculously sweet. Marvel announced the first Doomsday trailer confirmed McKellen and Stewart were returning for the new Marvel movie, alongside several other veterans of Fox’s X-Men movies, while He returns as Sam Wilson. The 8 Mile star started by describing just how surreal it was to see the pair on set.
