You may not have heard of jazz drumming Whiplash, but trust us when we see you'll never forget it once you've watched it.
It's a film that's managed to win Sundance - TWICE. Once as a short film, and then nabbing the top honours when it was remade as a feature film just 12 months later.
We sat down with the writer and director Damien Chazelle and star J.K. Simmons at this year's Cannes Film Festival to pick their thoughts on why it'll appeal to people who aren't in jazz drumming, the biggest challenge in making it, what they're most proud of and much more.
Whiplash will hit UK cinemas in 2014.
