With principal photography on AVENGERS: INFINITY WAR and AVENGERS 4 now wrapped, it's very likely that many of the most prominent characters in the Marvel Cinematic Universe have suited up for the last time. Marvel Studios president Kevin Feige has said that AVENGERS 4 will serve as the culmination of everything we've seen in the MCU up to this point, as well as offering us something never seen in superhero films: "a finale." One character who may be strolling across the rainbow bridge into the sunset is Thor (Chris Hemsworth), as the actor told USA Today that his original six-film contract with Marvel has now come to an end.
Contractually, right now — yeah, this is it. I’m done. I won’t be playing the character again. [It's] a scary thought. This really seemed like this never-ending thing. And now it’s potentially finishing.
After debuting in THOR, Chris Hemsworth went on to play the Asgardian God of Thunder in THE AVENGERS, THOR: THE DARK WORLD, AVENGERS: AGE OF ULTRON, DOCTOR STRANGE, THOR: RAGNAROK, as well as the upcoming AVENGERS: INFINITY WAR and AVENGERS 4. However, just because Chris Hemsworth's Marvel contract is completed, doesn't mean that we've seen the last of Thor. Given the amount of fun Hemsworth seemed to have making THOR: RAGNAROK with Taika Waititi, I'd bet on Thor making his return, assuming he survives the events of AVENGERS 4. "I felt like we re-invented him," said Hemsworth of his character in THOR: RAGNAROK, adding that Kevin Feige apparently told him that "There is a bigger platform now to continue if we want to."
"So who knows?" Hemsworth continued. "There are 76 cast members in these two Avengers films. They will be the biggest films of all time, far bigger than my character. It’s a conversation for further down the road, if it was going to happen." Signing on for a multi-film contract is quite the commitment, so I wouldn't hold it against Hemsworth if he decided to hang up the hammer and, hopefully, go out with a bang in AVENGERS 4. Kevin Feige has said that after the conclusion of AVENGERS 4, we'll be looking at the MCU as "two distinct periods. Everything before Avengers 4 and everything after. I know it will not be in ways people are expecting. 22 movies in, and we’ve got another 20 movies on the docket that are completely different from anything that’s come before—intentionally."
AVENGERS: INFINITY WAR will hit theaters on May 4, 2018, followed by AVENGERS 4 on May 3, 2019.
