Control
(2007)

Ian Curtis gets married to Debbie while they are teenagers.

Ian is a sensitive poet and suffers from epilepsy that can't seem to be controlled by medication.  He joins a band that becomes Joy Division,
a post punk rock band that influenced the melancholy alternative rock music of the 80s.

Ian and Debbie have a baby but Ian has an affair with a journalist named Annik.  Depression, seizures while performing on stage and a collapsing  marriage take their toll on Ian. 

Two days before the band is to leave for their first American tour, Ian kills himself at the age of 23.

Thanks Don P!
