Thanks partly to critical acclaim for Taxi Driver, Schrader was able to direct his first feature, Blue Collar (1978), co-written with his brother Leonard. Blue Collar features Richard Pryor, Harvey Keitel, and Yaphet Kotto as car factory workers attempting to escape their socio-economic rut through theft and blackmail. He has described the film as difficult to make, because of the artistic and personal tensions between him and the cast. During principal photography he suffered an on-set mental collapse which led him to seriously reconsider his career. John Milius acted as executive Producer on the following year's Hardcore, again written by Schrader, a film with many autobiographical parallels in his depiction of the Calvinist milieu of Grand Rapids, and in the character of George C. Scott, which was based on Schrader's father.
