Doctor Strange 2: 10 Multiverse Cameos That Would Break The Internet
5. Tom Cruise As Iron Man
In a What If-style alternate timeline that truly is bizarre to think about, there was a time when Tom Cruise was legitimately in the running to play Iron Man, well before Robert Downey Jr took on the role and made it his own.
So now that alternate timelines have become the MCU's latest gimmick, what's stopping Marvel Studios from roping in Cruise to play a variant Iron Man?
Well, just to play devil's advocate for a moment, Cruise himself might be stopping them. Would a mega-star like him sign up for a meaningless cameo? It seems unlikely, but then again, that's exactly what Brad Pitt did in Deadpool 2, and everybody loved it. Plus, Cruise has shown that he's open to a bit of goofing around with small roles - remember Les Grossman in Tropic Thunder?
Cruise popping up as an alternate-reality Iron Man has actually been rumoured for a while, and if there's one franchise that could get away with pulling an insane stunt like this, it's the MCU.
