The actor was present during Thor's return to Asgard and witnessed him forcing "Odin" to reveal that he was in fact Loki in disguise. He was one of the victims that perished in 2018 when Thanos used the Infinity Gauntlet to kill half the universe.

Behind the Scenes
- Matt Damon previously portrayed a character named Loki (based on the Norse god who inspired the Marvel character) in Kevin Smith's 1999 film Dogma.
- In an interview with Entertainment Weekly, Taika Waititi explained the reason for casting Matt Damon in the role: "Well Matt and Chris are very good friends. We were looking for someone to play Loki and it felt like if Loki was going to write a play about his death he’d want the star of the Asgard theater scene to be in the play." Kevin Feige revealed in an interview with Collider that Chris Hemsworth suggested casting Damon and Feige assumed that he was joking: "There was a fun idea of “Let's get Luke Hemsworth to play Thor,” Taika had worked with Sam Neill in Hunt for the Wilderpeople. He was willing to come in and do Odin. So who could be Loki? Who could be Loki? Who could be Loki? We didn't have any brilliant ideas. At one point, off handedly, Mr. Hemsworth goes, “Well what if I ask my friend Matt?” I said, “Matt who?” He said, “My friend, Matt Damon.” “Okay. Sure. Sure Chris, ask your friend Matt Damon. He’s not doing this. Oh he’s gonna do it. He's flying down.” The next thing I know, Matt Damon is on set in a full Loki costume, full Loki wig. We have pictures that maybe we’ll share some day of Tom Hiddleston in a full Loki outfit standing next to Matt Damon in full Loki outfit. It is very surreal and very amazing.".
