Sundance 2014: Whiplash wins jury and audience awards
The dramatic story of a drummer who pursues excellence at all costs won top honors at the Sundance film festival.
Whiplash collected both audience and jury prizes for American dramatic films at the festival's awards ceremony.
The musical drama by writer-director Damien Chazelle opened the independent film showcase last week and rode a wave of positive buzz throughout the 10-day event.
Chazelle made his Sundance debut last year with a short version of Whiplash intended to gain financial support for the feature-length film. The feature stars 26-year-old Miles Teller as an aspiring jazz drummer and veteran actor JK Simmons as his unforgiving instructor.
Chazelle thanked his actors "who really made this movie work". The 28-year-old filmmaker drew on his personal experiences as a member of a high school jazz band as inspiration for the film.
The documentary Rich Hill, a coming-of-age story about the inhabitants of a tiny town in Missouri, won the jury award for US documentary. The American documentary about music's healing effects on dementia, Alive Inside: A Story of Music & Memory, won the audience award.
Meanwhile, Australian director Sophie Hyde won the directing award for world cinema dramatic for 52 Tuesdays, which looks at how a teenage girl deals with mother's gender transition.
Actors Nick Offerman and Megan Mullally hosted the ceremony at the Basin Recreation Fieldhouse in Park City, Utah.
The 30th Sundance film festival finishes on Sunday 26 January.
