Marvel Studios went live at 11 a.m. EDT with a stream on Instagram and YouTube depicting a canvas directors chair with Chris Hemsworths name on it. The studios official account on X posted the stream with no context except the word ANNOUNCEMENT and the text take a seat. The stream is currently revealing further chairs one at a time at roughly 10-minute intervals, each featuring a new familiar name of an actor from the Marvel Cinematic Universe roster. The logical assumption is that were seeing a slow-burn reveal of the cast for Marvel Studios upcoming event movie Avengers: Doomsday, starring Robert Downey Jr. as Doctor Doom and probably as many Avengers as Marvel can cram on screen. (But not Dr. Strange, apparently.)As of this posting, weve seen chairs for Hemsworth (presumably returning as Thor), Vanessa Kirby (set to play Sue Storm, aka Invisible Woman, in Fantastic Four: Next Steps later this year), Anthony Mackie (fresh off his run as Captain America in Captain America: Brave New World), Sebastian Stan (as Bucky Barnes, aka Winter Soldier, who showed up for a cameo in Brave New World and will co-star in Thunderbolts* in May), and Letitia Wright (Shuri from the Black Panther movies).If the current pace continues, and the primary cast is as sprawling as it was for previous Avengers movies, we can expect this livestream to continue for hours, with fans mostly waiting to see whether supposedly retired MCU players like Chris Evans and Scarlett Johansson have been lured back into the game. (The latter is an extreme long-shot, given Johanssons recent interview where she emphasized that her MCU character, Black Widow, is dead, and that Marvel fans should move on.)But the real appeal in the stream and on social media is the raucous live-chat and run of memes, as Marvel fans with nothing to do but wait try to out-funny each other in expressing their impatience for the stream to move on. pic.twitter.com/B6JY1kIfvb arianators wildin (@arianatorswildt) March 26, 2025This post is being updated live as the stream continues. Avengers: Doomsday is scheduled for release in 2026.
