VIDEO : Sebastian Stan Does ?Soldier Training? for Avengers: Infinity War

A new video of Sebastian Stan training for his upcoming role in Avengers: Infinity War has appeared online, thus building excitement for the highly-anticipated superhero mashup. Ever since Marvel Studios showed their cards in the post-credits scene of Joss Whedon?s The Avengers in 2012, thus revealing Thanos, the Marvel Cinematic Universe has been building up to an ultimate showdown between Earth?s Mightiest Heroes and the Mad Titan (Josh Brolin). That confrontation begins in Anthony and Joe Russo?s Avengers: Infinity War next year.
