"The Big Wedding" Trailer #3

The ensemble comedy stars Robert De Niro, Katherine Heigl, Diane Keaton, Amanda Seyfried, Topher Grace, Susan Sarandon, Robin Williams, Ben Barnes, Christine Ebersole, David Rasche, Patricia Rae and Ana Ayora and follows a charmingly modern family trying to survive a weekend wedding celebration that has the potential to become a full blown family fiasco. To the amusement of their adult children and friends, long divorced couple Don and Ellie Griffin (De Niro and Keaton) are once again forced to play the happy couple for the sake of their adopted son's wedding after his ultra conservative biological mother unexpectedly decides to fly halfway across the world to attend. With all of the wedding guests looking on, the Griffins are hilariously forced to confront their past, present and future - and hopefully avoid killing each other in the process.
