Moreover, Coppola's casting process often involves extensive rehearsals and improvisation, allowing actors to explore their characters in depth. This collaborative approach enables him to build trust with his cast and encourages them to push beyond their comfort zones. For example, during the rehearsals for "The Conversation" (1974), Gene Hackman and Robert Duvall worked closely with Coppola to develop their characters, leading to performances that were both naturalistic and deeply affecting.
