Avengers: Endgame directors Joe and Anthony Russo have explained more about Captain America's time-travelling escapades in the 2019 MCU movie.As reported by CinemaBlend, the Russo brothers addressed the timeline travelling in Avengers: Endgame during a recent guest appearance on the Lights Camera Barstool podcast. According to the pair, Captain America did, in fact, live out his days with Hayley Atwell's Peggy Carter in an alternate "branch" of reality before travelling back to the main timeline to handover his iconic shield."One thing that's clear that Anthony and I have discussed, I don't know that we've discussed this publicly at all, Cap would have had to have travelled back to the main timeline," Joe explained in the interview. "That's something that, yes, he would have been in a branch reality, but he would have to travel back to the main timeline to give that shield to Sam Wilson."He further explained the logistics of the time jump: "In our internal logic that we defined in the room, that was the choice that we made, was based on everything that happened he would have been in a branch reality and then had to have shifted over to this, so jumped from one to the other, right, and handed the shield off."The Endgame directors wrapped up Steve Roger's MCU journey on a very definitive note, with Steve travelling back in time to return the Infinity Stones to their original places and then choosing to remain in the past to finally take up the dance that he had initially promised Peggy in Captain America: The First Avenger. However, when he returns to the rest of our heroes, he is an old man.The previously established rules of time-travel in Endgame made this ending pretty confusing, but the end result is that Steve is alive in the present, living as a senior citizen, when he returns to bestow his shield upon his winged, crime-fighting partner Sam Wilson, AKA Falcon, who has also been known to take up the mantle of Captain America in the comics.Anthony Mackie will soon be back on our screens as he reprises his role as Falcon in the upcoming Disney+ original series The Falcon and the Winter Soldier, opposite Sebastian Stan, who plays Bucky Barnes. The six-episode series is set to debut on Disney+ on March 19, as part of an ambitious new lineup of TV series' designed to be more closely integrated with Marvel's movies.For more about the studio's future slate of projects and releases, read our breakdown of the biggest and most noteworthy developments in the MCU, on Disney+, and in Marvel's comics this year.Adele Ankers is a Freelance Entertainment Journalist.
