A video of Zoe Saldana (Gamora) that was released previously has resurfaced, and it suggests that the plot of “Avengers 4” will include time travel. The return of the actress in the upcoming film is yet to be confirmed, but the video suggests that she will be back. However, she may be seen in a different time period.

The video that Saldana posted before the premiere of “Infinity War” looked innocent at the time [see below]. The video just shows the actress in the makeup chair, getting ready to film her scenes. However, according to a report by ComicBook.com one fan noticed something interesting about her costume that appears to give a clue about the plot of the next movie.

Saldana’s costume in the video is similar to the one she wore for the first “Guardians of the Galaxy” movie. In one of the deleted scenes of “Infinity War” Gamora is seen in a similar costume, but it’s the hairstyle that gave it away.

In a deleted scene of “Infinity War” Gamora can indeed be seen wearing a similar dress, as she tosses the head of a king at Thanos’ (Josh Brolin). However, she has a different hairstyle in that scene. In the video that Saldana posted online, the actress appears to be sporting the hairstyle she had in “Guardians of the Galaxy,” which suggests that someone will go back in time to warn all the superheroes about the Thanos threat.

It will be interesting to see how the heroes will manage to go back in time, if this is indeed the plot of the next film. Also, will it be just one person going back in time or will it be a group?

Doctor Strange (Benedict Cumberbatch), who has already seen all possible futures, and said in “Infinity War” that Tony Stark (Robert Downey Jr.) is the key to saving the future. It remains to be seen how exactly he will fix what Thanos has done.
