Dearly beloved, we are gathered here to witness an all star cast caught in various compromising positions over one chaotic wedding weekend. Robert De Niro and Diane Keaton play Don and Ellie, a long-divorced couple whose adopted son (Ben Barnes) asks them to pretend to be married to keep his Catholic biological mother happy when she arrives from Colombia for his big day with Missy (Amanda Seyfried). The roguish Don has no good reason to refuse. But as the charades begin, his girlfriend (Susan Sarandon), estranged daughter (Katherine Heigl), and 29-year-old virgin other son (Topher Grace) find it hard to hold their peace.
