Iron Man in Sam Raimi’s Spider-Man

  • Description: Initially, in Sam Raimi’s Spider-Man 2, Iron Man was supposed to play a major role. It is said that Tony Stark would have helped Dr. Octopus in building his robotic arms. However, this would have been shown somewhere in the 2008 Iron Man outing. 
  • How It Was Done: The plan was, however, dropped later, with the reason still being unknown. It is believed that the low reception of Spider-Man 3 would have played a major role. 
  • Why It’s Interesting: Having Robert Downey Jr.’s role in Tobey Maguire’s Spider-Man would be very intriguing for all the fans of Marvel comics.

Gal Gadot for Nebula

  • Description: Before the role of Nebula in the Guardians of the Galaxy went to Karen Gillan, who without a doubt delivered a perfect portrayal of the character, it was first offered to Gal Gadot. While we are all in love with the actress for her screen time in the DCEU, the MCU was supposed to be her first outing as a superhero.
  • How It Was Done: This was a near-miss opportunity that would have had a totally different feel. When the negotiations fell through over the budget of the film, Gillian was chosen over Gadot.
  • Why It’s Interesting: Well, it isn't just limited to the MCU; we would have had a totally different-looking team in the DCEU.
  • Fun Fact: Another highly interesting event was that Jason Momoa was previously being considered for Drax. Well, it looks like the MCU would have had its own Justice League.
