Marvels slow burn reveal of theAvengers: Doomsday cast was a very clever feat of marketing. 100,000fans were glued to a live feed of some directors chairs on YouTube for an entire afternoon. The names on those directors chairs ranged from the obvious to the genuinely surprising.Some of the biggest surprises of the day, though, were the names thatdidntshow up on those chairs before Robert Downey Jr. walked into the shot to bring the live feed to a close. While more Marvel heroes and villains will surely appear inDoomsday than were confirmed today,the first 27 (!) namesin theDoomsday cast focused primarily on a few former Avengers, plus the casts ofThunderbolts,The Fantastic Four: First Steps, and the old Fox X-Men movies. That meant itdid notmention some of Marvels biggest stars, including some men and women who have appeared in a dozen or more MCU films and series, and talents who have headlined the studios biggest box-office hits.Now, this is Marvel were talking about; the only thing they like more than surprising people is by engineering an elaboratedeception to surprise people. Remember:This is the company that denied the rumors that Tobey Maguire and Andrew Garfield were inSpider-Man: No Way Home until the day the film opened in theaters! I wouldnt put it past them to do it again. So just because an actor wasntlisted inAvengers; Doomsdays official cast doesnt mean he wont be in the movie. But for now, here are 15 names were genuinely surprised were left out of the initial announcement.Marvel Characters Who Arent in Avengers: DoomsdaySome of Marvels most popular stars were no-shows in the Avengers: Doomsday cast list.READ MORE: What One Man Learned Reading Every Since Marvel Comic Ever PublishedGet our free mobile appThe Best Marvel Movies Not Made By Marvel Studios
