Marvel's cast-reveal livestream breaks a record: 275 million views
March 26, 2025
Marvel didn’t just announce the Avengers: Doomsday cast - it turned it into an event. As production began in March 2025, the studio ran a marathon livestream that slowly revealed the cast the only way that could sustain hours of attention: name cards on chairs, unveiled one at a time.
It worked. The stream pulled a staggering 275 million views - a Marvel Studios record - as fans watched, gasped and screenshotted their way through a roster that kept getting bigger: the returning X-Men, the Fantastic Four, the Thunderbolts, Loki, and more.
The genius was in the restraint. No trailer, no footage - just anticipation, stretched to breaking point. It also set the template for the whole campaign: tease relentlessly, confirm slowly, and keep the biggest question - what is Robert Downey Jr.’s Doctor Doom actually planning? - locked away.
See who made the final list in the cast guide, or start with the reveal that started it all: why RDJ is playing Doom.
