10 Ways MCU Movies Nearly Turned Out Completely Different

10. Thor Vs The Midgard Serpent - Avengers: Infinity War

After two films that truly built the Avengers into Earth's Mightiest Heroes, Captain America: Civil War broke the team up, and Avengers: Infinity War scattered them across the galaxy. Tony and Peter went to Titan to fight Thanos with the Guardians and Doctor Strange, and Cap and the majority of the team took the fight straight to Wakanda, while Thor joined forces with Rocket and Groot.

The God of Thunder, along with Rabbit and Tree, travelled to Nidavellir to forge a Thanos killing weapon before heading back to Earth. However, this wasn't always how Stormbreaker found its way into Thor's hand.

Instead, Chris Hemsworth's character and his companions were originally set to fight a giant multi-headed serpent thought to be the Norse legend Jormungand, as something of a test to prove that he was worthy of Stormbreaker. Though the same rules surrounding Mjolnir don't apply to Thor's new weapon, he would have had to get through the monster in order to find it.

According to screenwriters Stephen McFeely and Christopher Markus, the arc was dropped as it felt too adventure heavy. This was probably for the best, as this way we wouldn't have got to see Peter Dinklage's Eitri, or seen Groot create the handle for the Thanos killing axe.
