As for Sebastian Stan’s initial reaction to my question, there actually is good reason why he should be happy he made it into the Avengers: Infinity War trailer — specifically the fact that not everybody did.
Last Wednesday I wrote a feature about all of the key Marvel characters who didn’t get a spotlight moment in the footage, and it was a list that included big names like Jeremy Renner’s Hawkeye and Samuel L. Jackson’s Nick Fury.
Winter Soldier actually gets a couple of standout moments, first prepping his gun while standing alongside the Wakandan army, and the second charging into battle along with most of the other Avengers.
