Christopher Nolan's ( The Dark Knight trilogy, Inception ) eagerly anticipated Interstellar is a little over a month away, and while the film has been surrounded in secrecy, we now know its runtime! Hit the jump to find out how long you'll be in the theatre for...

Promotion for Christopher Nolan's Interstellar has kicked up a notch, and it seems theatres are getting more details on the extremely hush-hush movie. Australian company Event Cinemas has listed on their website that the film will run for 169 minutes, which makes it Nolan's longest picture to date. It beats out 2012's The Dark Knight Rises by just four minutes, but comes close to a three-hour runtime. Well, no matter the length, Interstellar is certainly going to have butts in seats when it arrives on November 7th.
