The Big Wedding

Don (Robert De Niro) and Ellie (Diane Keaton) are a long-divorced middle-aged couple who are forced by circumstance to pretend that they are still happily married as they attend their son's wedding. As the ramifications of their elaborate hoax unfold among their family and friends, a poignantly funny story emerges about the comedy and complexity of the tangled ties that bind. (Lionsgate UK)
