Whiplash

Whiplash is a 2014 American psychological drama film written and directed by Damien Chazelle, and starring Miles Teller, J. K. Simmons, Paul Reiser, and Melissa Benoist. The story follows ambitious jazz drummer Andrew Neiman (Teller), who is pushed to his limit by his abusive and ruthlessly strict bandleader (Simmons) at the fictional Shaffer Conservatory. After Chazelle completed the script of Whiplash, Right of Way Films and Blumhouse Productions helped him turn 15 pages of the script into an 18-minute short film, also titled Whiplash. The short film received acclaim after debuting at the 2013 Sundance Film Festival, which attracted investors to produce the complete version of the script... While attending Princeton High School, writer-director Damien Chazelle was in a "very competitive" jazz band and drew on the dread he felt in those years.[5] He based the conductor, Terence Fletcher, on his former band instructor (who died in 2003) but "pushed it further", adding elements of Buddy Rich and other band leaders known for their harsh treatment.[5] Chazelle said he wrote the film "initially in frustration" while trying to get his musical La La Land off the ground. https://en.wikipedia.org/wiki/Whiplash_(2014_film)
