Whiplash tells the story of a young music student who aspires to be a professional jazz drummer and his cruel teacher who consistently pushes him (and the other students) to the edge. Damien Chazelle, the mind behind multiple critically acclaimed movies, including La La Land, First Man, and Babylon, directed and wrote Whiplash, and addressed the possibility of the movie being based on a true story.
