Throughout its nearly two decades of existence, the Marvel Cinematic Universe has become synonymous with constantly releasing new content in theaters and streaming with a Disney+ subscription. But in order to guard against spoilers Marvel security is famously tight, especially for upcoming MCU movies. And Loki actor Tom Hiddleston recently revealed why he was so happy with the Doomsday cast announcement with all those chairs. What we know about Avengers: Doomsday is limited, but back in March of 2025 the majority of the movie's cast was revealed in a viral announcement. Hiddleston's return as Loki was confirmed in the process, and during an interview with ScreenRant the 45 year-old actor he shared why he was so happy to be included in that live stream. In his words: You know, I was just so relieved when I saw my name on the back of a chair. Because it meant I'd be like 'Okay, Marvel have let everybody know that I'm in it. So I don't have to pretend that I'm not in it.' Which I've had to do sometimes. Points were made. Hiddleston has been in the MCU since the OG Avengers back in 2012, so he's had plenty of experience guarding the shared universe's secrets. Luckily for him, his role in Doomsday was confirmed a while back. As such, he didn't have to spend the last year denying it in interviews. And after seeing how Andrew Garfield lied about his Spider-Man: No Way Home role, I can't blame the Loki star for his feelings.Fans who spent years watching the Marvel movies in order know how seriously most actors take spoilers, so it's understandable that Tom Hiddleston is feeling relieved about his Doomsday role being out in the open. In the same interview he went on to share:Endgame especially. Because I knew about that. I knew that I was in Endgame before Infinity War was released. And of course, Loki has a tough time in Infinity War. So that was a tricky one. This has been a little gentler. Because I can say that I'm in it. As we know, not all Marvel actors are so good at keeping secrets. Tom Holland has spoiled a number of things over the years, and Mark Ruffalo even revealed Infinity War's ending prior to it hitting theaters. It's unclear what Loki will be doing in Doomsday, but we've seen a few brief glimpses of him in his TVA jacket. And while his role was confirmed, Tom Hiddleston is still keeping his cards close the chest. As he put it: But if you're asking me to tell you more about Avengers: Doomsday my lips are sealed. Smart man. We'll just have to wait and see how Loki factors into the story of the next Avengers movie. Luckily we're getting ever-closer to that movie's release this winter. So hopefully we get more footage of the God of Mischief sooner rather than later. All will be revealed when Avengers: Doomsday hits theaters on December 18th as part of the 2026 movie release list. Let's just hope Loki doesn't get killed off yet again in the process. Fingers crossed.
