The Hollywood veteran passed away last month (Sep11) at the age of 81 and his friends, family and colleagues came together to celebrate his achievements at the Sony Pictures Studios in California.
Beatty was one of the speakers at the event, which took place on a studio soundstage, along with Desperate Housewives star Dana Delany and Mel Brooks.
Sony Pictures co-chair Amy Pascal also spoke at the memorial and introduced a video of tribute from stars including Maria Bello and Natalie Portman, who recalled Calley's career advice to her.
In the clip, the actress said Calley told her, ""Don't go after the money. It leads to loneliness. Do it for the love and a great life.""
The memorial came just a day after Sony Pictures bosses announced they will be naming a park at the company's Culver City base after the former studio chairman.
