Paramount executives were adamant that Brando not be hired to play Vito Corleone because of the actor's reputation for problems on set. Finally, they relented by providing conditions that they thought could never be met, including that Brando give them a screen test. Director Francis Ford Coppola told Brando he wanted to test equipment and get a sample take, very carefully not phrasing the filming as a screen test. When the take had been filmed, even Brando was happy with it, saying he thought he'd gotten the appearance of being "mean-looking, but warm underneath." In later years, Brando said he'd known all along it was a screen test.
