Thanks to director Justin Zackham (screenwriter and executive producer of The Bucket List), Oscar-winning actors Robert De Niro and Robin Williams are reunited on screen. In Big Wedding (previously known as Gently Down the Stream), De Niro plays Don Griffin, a family man who, with his ex-wife Ellie (Diane Keaton), decides to pretend they're still together for the sake of their adopted son (Ben Barnes), who is about to get married. This decision comes after they learn that the boy's biological mother, a very religious and narrow-minded woman, will be among the wedding guests. But with a priest like Robin Williams and an explosive ex-girlfriend like Susan Sarandon, the ceremony is unlikely to go as planned.
