Kevin Feige apparently forgot to send the Marvel Snipers up to Toronto for TIFF because Collider got to ask Sebastian Stan, up there for The Martian, questions about Captain America: Civil War and he did not no-comment his way out of it.
Most of it is fanboying over CA:TWS, but of note for the future:
* The Ant-Man post-credits scene is a straight-up excerpt from CA:CW and, Stan estimates, it’s probably mid-movie.
* Nobody is sure which side the Winter Soldier/Bucky Barnes is on, he says. Presumably, this is not a confusion that lasts forever, but in light of the above, it is maybe a confusion that lasts for the first half of the movie. Maybe all of it.
* He explicitly states that CA:CW is not Avengers 2.5, but instead a Russos-shaped Cap movie.
* And, on the aesthetics front, the look he’s currently sporting is Marvel-required (presumably for reshoots) and he’d kinda like to cut his hair.
