10 Actors Who Almost Played 2019's Biggest Roles

10. So Many Stars - Avengers: Endgame

Okay, so this first entry is a little bit of a cheat, however, with Avengers: Endgame already the biggest movie of the year and clipping at Avatar's heels to become the biggest movie of all time, so it can't be left out.

When your blockbusters are as massive and popular as Marvel Studios', you have an enormous amount of big name stars linked to everything you produce.

Husband and wife John Krasinski and Emily Blunt could have shared the final scene of Endgame together had casting turned out differently, with Krasinski up for the role of Captain America and Blunt for the role of his betrothed; Peggy Carter.

The list of potential Peter Quill candidates was rife with talent, with Joseph Gordon-Levitt, Wes Bentley, and Glenn Howerton of It's Always Sunny In Philadelphia fame all in with a shot at playing the self-proclaimed legendary outlaw.

The Hemsworth family were seemingly destined to have a substantial role in the MCU, with Chris' brother Liam reportedly linked with the role of Thor.

Finally, the competition Tom Holland faced to play the friendly neighbourhood Spider-Man included Oscar nominee Timothee Chalamet and Sex Education lead Asa Butterfield.
