Absolution (1978)

At a Catholic boys’ school, domineering disciplinarian Father Goddard rules over his pupils with an iron hand. When one of his teenage charges confesses to murder, the dogmatic but deeply repressed Goddard finds his faith challenged and his life spiralling dangerously out of control. Also starring Billy Connolly (in his first feature-film role), Dominic Guard ,Kes star Dai Bradley, and the inimitable Brian Glover, and written by the great Anthony Shaffer, Absolution is one of British cinema’s most underrated chillers, not least for a towering central performance by Burton.
