Chris Hemsworth says that he was looking for a character based project when Rush came along.
The actor is set to take on the role of F1 driver James Hunt in the new Ron Howard directed film; which follows the rivalry between Hunt and Niki Lauda.
Hemsworth says he was excited to work with Ron Howard as well as make a movie that was set to an F1 background.
Speaking to Total Film the actor said: "The focus was certainly to do something character based and rooted in reality.
"I love the fantasy world that I was working in for Thor and Snow White & The Huntsman but, you know, I had it in spades. So something like this was essential, just for my own personal growth.
"When [Rush] came along, it ticked every box - from [working with] one of my favourite directors to a story that instantly fascinated me...
"You have this incredibly exciting backdrop of F1 and the sexiness and excitement of the ’70s, but with a beautiful character story at the centre of it."
It is going to be a busy autumn for the actor as we are going to be seeing him in Rush and Thor: The Dark World.
He is currently filming Cyber, which is the new film for director Michael Mann, with Viola Davis.
Rush is released 13th September.
