At 52 years old, wrestler-turned-Marvel action hero Dave Bautista is in better shape than most 22-year-olds. But he’s still a little self-conscious about his appearance. As a recent guest on Ellen, the Guardians of the Galaxy star confessed to the host that his alien alter ego’s aversion to shirts is one of the reasons he’s exiting the Marvel Cinematic Universe franchise after the upcoming third installment. “I’m going to be 54 years old by the time Guardians 3 comes out,” he told DeGeneres about why he’ll no longer play Drax the Destroyer. “The shirtless thing is getting harder and harder for me.”a close up of an animal: Dave Bautista flexes his acting muscles as Drax the Destroyer in 2014's 'Guardians of the Galaxy' (Photo: ©Walt Disney Co./Courtesy Everett Collection) Dave Bautista flexes his acting muscles as Drax the Destroyer in 2014’s ‘Guardians of the Galaxy’ (Photo: ©Walt Disney Co./Courtesy Everett Collection)Bautista was the breakout star of the Guardians‘ inaugural 2014 adventure as well as the 2017 sequel, both of which were written and directed by James Gunn. And he’s long credited Gunn with taking a chance on him when he was still a big-screen novice. “I struggled, I starved for three years, I could barely get a job,” he remarked in a 2018 interview. “There were a few people who believed in me along the way, but James was the one who really changed the course of my life.”

Bautista was so devoted to Gunn that he almost walked away from the franchise entirely when Marvel fired the writer/director from Guardians of the Galaxy, Vol. 3 in 2018 following the resurfacing of some controversial tweets. “I’m not okay with what’s happening to him,” the actor wrote on social media at the time, joining the rest of the Guardians cast in signing an open letter expressing regret about the situation. Gunn was ultimately rehired in 2019, and Vol. 3 is expected to start shooting later this year after the release of his DC Comics-based movie, The Suicide Squad. It’s currently scheduled to arrive in theaters on May 5, 2023 as part of Marvel’s Phase 4 lineup.

On Ellen, Bautista said that Gunn is likely stepping away from the MCU following the final Guardians installment, and where he goes, Drax will follow. “We work in trilogies,” Bautista explained. “James Gunn has already announced it’s his last film, and when James is done, I’m done. The journey has come full circle and I’m just ready to step aside and wrap it up.”

He’s currently starring in Zack Snyder’s zombie heist film, Army of the Dead, which hits Netflix on May 21. And as the leader of the movie’s zombie-killing crew, he gets to keep his shirt on. “I wanted to be the leader, it was something I chased after,” he told Yahoo Entertainment recently. “But I never felt like I was the center of attention on set, because if you watch the film, you see that every character gets their moment to shine. Usually supporting character get lost in the shuffle. Zack did a great job making sure every character was highlighted, and the film is this roller coaster ride of fun. I’m super-proud of it.”

Both Guardians of the Galaxy movies are streaming on Disney+.
