Captain America: Civil War - 8 Things We Learned From Team Iron Man On Jimmy Kimmel
4. Bucky DOES Try To Kill
When the shot from the trailer of Bucky trying to shoot Tony Stark emerged, it seemed that his pulling the trigger (which Tony's cool watch gauntlet catches) might have just been an expression of their personal friction) but the extended clip shown during the interviews of the same sequence painted a different light.
Not only does Bucky try and shoot what appears to be an innocent UN security staffer, he also attempts to throttle Black Widow after fighting Sharon Carter. The fact that Widow then says "you could at least recognise me" suggests that this is Bucky still under the assassin's fog.
So is Bucky actually behind the explosion at the UN building? Or is it just his confused commitment to his target that makes him look the villain? Either way, the short segment of footage changes a lot.
