20 Things You Didn't Know About Interstellar
9. Matt Damon's Role Made Him Wary About Starring In The Martian
In the years since, many jokes have been made about Matt Damon's similar roles in Interstellar and The Martian - a similarity that's compounded by the fact that both movies hit cinemas just 11 months apart.
Each movie sees Damon assume the role of an astronaut stuck on a barren planet, a funny coincidence the actor himself is well aware of.
In his initial chats with The Martian director Ridley Scott, Damon told him that - because of those Interstellar similarities - he wasn't sure if he could do the movie.
His fears didn't last for long though, because, in response, Scott told him that "Nobody gives a sh*t about that" - and the rest is history.
