With the support of director Otto Preminger, Trumbo was credited for his screenplay for the 1960 film Exodus, which he adapted from the novel by Leon Uris. Shortly thereafter, Kirk Douglas made public Trumbo's writing of the screenplay for Stanley Kubrick's film Spartacus (1960) starring Douglas,[25] an event which has been cited as the beginning of the end of the blacklist. Trumbo was reinstated into the Writers Guild of America, West, and was credited on all subsequent scripts.
