The Big Wedding 2013

Don and Ellie Griffin (Robert De Niro and Diane Keaton), long divorced, are suddenly thrown back together for the sake of their adopted son's wedding when his very conservative biological mother decides to come in for the nuptials. The Griffin's soon learn that acting the happily married couple is not so easy and especially awkward for Don's girlfriend, Bebe (Susan Sarandon). In the midst of these charades, the Griffin's children face their own troubles as Lyla (Katherine Heigl) struggles with a secret, Jared (Topher Grace) contemplates his love life or lack thereof, and Alejandro (Ben Barnes) tries to keep everyone together, including his new bride, Missy (Amanda Seyfried) who is appeasing her parents by getting married by a priest (Robin Williams) in a traditional Catholic wedding.
