When speaking with Chris Evans on the set of Avengers: Age of Ultron in the summer of 2014, back when he was publicly stating in interviews that he was ready to leave acting behind once his six-picture deal with Marvel Studios was honored, he raised a point about how easy it is to see the larger paths of the franchise's major characters. One could look at the contract lengths of the individual Avengers to see where they should and shouldn't be appearing.
Perhaps it's this reality that made Marvel ask its talent to no longer specify how many films they've signed up for; why the likes of Chris Pratt, Paul Bettany, Anthony Mackie, and Elizabeth Olsen, etc. won't answer questions about that number. For the original Avengers, we knew exactly though, but even this number has changed drastically as Marvel's Phase 3 continues to change. Robert Downey Jr. signed extensions at least three times that we know of, and now, even Evans has changed his tune and is excited at the possibility of doing more Marvel work beyond Avengers: Infinity War.
That Avengers movie event, the two-part conclusion to Phase 3, is where the contracts for most of the original Avengers cast members were originally intended to end. It's also this story that makes it hard to see many of Marvel's big screen heroes being killed off over the next three years of releases. They all need to be there to fight Thanos in 2018 and 2019, right? Perhaps not.
NOTE: The following post contains potential SPOILERS for Captain America: Civil War.
Captain America: Civil War directors Anthony and Joe Russo, who got their big screen breakout directing The Winter Soldier and are already working again on Infinity War (script update here!), have consistently talked about continuing to raise the stakes with these movies and promise a "seismic shift" in the MCU with Captain America 3. With that in mind, we have a news bit coming from That Hashtag Show that builds off their last scoop which claimed that Civil War will both begin and end with funeral scenes, the latter of which will be for Steve Rogers.
That point wasn't groundbreaking, given that Steve Rogers died at the end of the Marvel Civil War crossover event in the comics that the film is based on - and we know it's a ploy for him to return later. Now, the YouTube show is claiming multiple "death" scenes were shot during production of Captain America: Civil War for other characters (Scarlet Witch, Falcon, and War Machine) and that only one of these will appear in the theatrical release.
