While fans are still wondering what's going on with Avengers: Infinity War, production at Marvel Studios has already moved on to Avengers 4. However, a new image has given us an idea of what to expect in that movie, at least in one scene. The movie is filming in and around Pinewood Studios in Atlanta right now and just before Thanksgiving, they were filming on a public street using decades-old automobiles, which would seem to indicate that the new movie will do some time jumping.
The image posted by the Atlanta Journal-Constitution is pretty simple showing a classic car at the end of a road surrounded by autumn trees. However, the story does state that Chris Evans is also on the set, which would seem to indicate the scene is designed to look like something out of Captain America: The First Avenger. The car would certainly match with that look.
There are two possibilities for how this scene may play out in Avengers 4. The first is as a simple flashback. The scene could even be part of Steve Rogers life before he took the super soldier serum. However, the much more interesting possibility is that it could mean Avengers 4 could actually include time travel. As we saw in Doctor Strange, the time stone is capable of shifting time and while we only saw simple time jumps in that film, once Thanos has all the Infinity Stones, one assumes he could seriously mess with the timeline.
However the scene is handled, it could indicate that one of the strongest rumors surrounding the Avengers films could turn out to be true. There has been a lot of speculation and circumstantial evidence that Hayley Atwell, who played Agent Carter in the previous Captain America films, could be making an appearance in either one of the new Avengers films, or possibly both. A scene that takes Captain America back to the 1940s, either via time travel or flashback, would very likely include other characters that we'd recognize from that era of the first Captain America film, and Agent Carter would be the most likely.
Of course, if the scene being depicted is time travel rather than simply a flashback, it could also indicate a lot more for the future of the Marvel Cinematic Universe. Time travel would mean the potential for changes to the timeline, so we could come out of Avengers 4 with an MCU that potentially looks different than the one that we saw going into the movie. We'll get our first hint of this when Avengers 3 arrives in May, followed by the still untitled Avengers 4 a year later.
