Just been looking at the cast list on IMDB.
Looks like Bucky will be in it:

Sebastian Stan


Also, I saw that Jackson will be in it as Fury and assumed that it would maybe be in the modern day, but seeing as Dum Dum Duggan is in it, then we may have WWII Fury instead.

Dum Dum = Neal McDonough


Peggy Carter = Hayley Atwell


Also, Tommy Lee Jones as Gen. Chester Phillips.

Snarf is shit. His death will be rejoiced!
