Mark Ruffalo<\/a> didn’t give anything away this time.<\/p>\n The Oscar-nominated actor was a guest on Thursday’s episode of The Tonight Show Starring Jimmy Fallon<\/a>, where there host teased him about why he hasn’t been mentioned as part of the cast for Marvel’s upcoming movie Avengers: Doomsday<\/a>.<\/p>\n That’s despite the fact that the Task star has played the comic-book character of the Hulk and his alter ego Bruce Banner in several previous films of the franchise.<\/p>\n “Can you say why you weren’t in the Avengers trailer?” Fallon asked him. “Every time you’re on the show, you give a spoiler and you get in trouble.”<\/p>\n Ruffalo answered, “They decided that it was better to get rid of me than for me to tell the end of the next movie.”<\/p>\n To which Fallon responded, “All right, that makes sense.”<\/p>\n The late-night host has a point. Ruffalo has a history of saying too much about his superhero films, though it isn’t always on Fallon’s NBC show.<\/p>\n For instance, he did it on Instagram in October 2017, when he accidentally live-streamed part of Thor: Ragnarok.<\/p>\n In May 2018, it became clear he had spilled details on the ending of Avengers: Infinity War months before the movie was released.<\/p>\n “Wait ’til you see this next one,” Ruffalo had told Good Morning America at the D23 convention. “Ha\u2026 everybody dies.” He then says half of them die, which was accurate.<\/p>\n Marvel Studios<\/p>\n Mark Ruffalo in 2019’s ‘Avengers: Endgame’<\/p><\/div>\n Get your daily dose of entertainment news, celebrity updates, and what to watch with our EW Dispatch newsletter<\/a>.<\/strong><\/p>\n His interview partner, costar Don Cheadle, cut in immediately: “Dude! Dude.” Ruffalo attempted to recover and even asked, “Can we rewind that part?”<\/p>\n There have been other times.<\/p>\n However, it’s unclear whether Ruffalo will be part of the Avengers: Doomsday cast, which features countless of his fellow Marvel stars. The official cast announcement<\/a>, released in March, included dozens of alums from the studio’s projects, such as Chris Hemsworth; Simu Liu; Robert Downey Jr.; Letitia Wright; Anthony Mackie; Ian McKellen; Vanessa Kirby; and Florence Pugh.<\/p>\n Ruffalo will reprise his role in next year’s Spider-Man: Brand New Day, which stars Tom Holland. The film is set to be released on Dec. 18, 2026.<\/p>\n EW has reached out to Marvel for comment.<\/p>\n<\/span><\/div>\n
