Avengers 4: Mysterious Teaser Image Released As Filming Finishes

Avengers 4 has finally finishing filming, directors Joe and Anthony Russo announced on Twitter. That's an exciting and important milestone in the film's production, but perhaps the more intriguing element here is the image that that brothers shared.

The mysterious image depicts a bright blue light that apparently has some kind of connection to something that happens in the untitled fourth Avengers film.

The follow-up to Infinity War is set to hit theatres in April 2019, following the release of the Brie Larson-starring Captain Marvel in March 2019. The new Avengers movie will seemingly wrap up a years-long story arc following the dramatic events of Infinity War.

Chris Evans, who plays Steve Rogers/Captain America, recently talked about his emotional final day on set. Some Marvel fans believe Cap might be among the characters who could be killed off in the new Avengers film.

According to ComicBook.com, Evans recently recalled at the ACE Comic Con in Chicago how the final line he recorded for Avengers 4 was "something really stupid" that he cannot talk about. Importantly, this was a scene he came back to set to film as a pick-up, so it's not the final line his character says in the film. "It might have been a line to Paul Rudd. He wasn't there, but it was a stupid line. The line wasn't memorable to me [laughs]. The day was more memorable than the line," Evans said.

Writer Christopher Markus said the next Avengers film will be very different, summarizing it as: "We broke your heart. Now we're going to blow your mind."
