The fourth Avengers film is currently being filmed, and Jeremy Renner has seemingly confirmed that he will return in it as Clint Barton, aka Hawkeye.
On his Instagram page, Renner posted a picture of his shadow, the silhouette of which clearly shows him wearing the superhero outfit. “Costume on point today … what do you think?” he asks.
The currently untitled fourth Avengers film will be out on May 3, 2019, and serve as a “part 2” of Avengers: Infinity War, which will be released on May 4 of next year. The two films will see the Avengers team up with the Guardians of the Galaxy to fight the Mad Titan Thanos, a powerful alien who wishes to collect the six Infinity Gems and place them into his Infinity Gauntlet; doing so will give him virtually unlimited power, spelling doom for the universe.
Fans expect for Thanos and his servants, the Black Order, to kill at least one major character before the saga is complete. Many have focused on Hawkeye as a probable target: he lacks superpowers (save amazing archery skills) and does not have his own film series, nor has he been as prominent in the franchise as fellow Avenger Black Widow. This post, however, implies that he will at least live through Avengers: Infinity War.
Hawkeye was also notably absent from the Avengers: Infinity War trailer, perhaps implying a mystery or twist for his role in that film.
