William Friedkin, Jason Miller, and Warner Bros. / 1970s
Warner Bros. executives were uneasy with William Friedkin and William Peter Blatty's decision to cast relatively unknown performers in a film expected to carry a major studio's prestige and financial risk. The studio had already signed Stacy Keach to play Father Damien Karras, while A-list possibilities such as Jack Nicholson and Paul Newman had been considered. Friedkin, however, became convinced that Jason Miller—an experienced stage actor and playwright with a Catholic education and a personal history of studying for the Jesuit priesthood—possessed the haunted, spiritually divided quality the role required.
Miller had first met Friedkin after a performance of his play That Championship Season and told the director, after reading Blatty's novel, that Karras was essentially himself. Friedkin initially told him the part was taken, but arranged a screen test in which Miller performed with Ellen Burstyn and recited the Mass as if encountering it for the first time. After viewing the footage, Friedkin concluded that Miller's quiet intensity and troubled spirituality were ideal for the role. Warner Bros. ultimately bought out Keach's contract and installed Miller, a costly and risky reversal that became one of the film's defining casting decisions. The same battle played out over Burstyn, whom studio chief Ted Ashley strongly opposed before relenting, and Linda Blair, whose lack of major acting credits made executives even more doubtful.
