All-Stars Assemble for 'The Big Wedding'

By
Hollywood's finest has assembled for the all-star comedy The Big Wedding, in theaters April 26, and we've got a look behind the scenes!
Robert De Niro, Katherine Heigl, Diane Keaton, Amanda Seyfried, Topher Grace, Susan Sarandon and Robin Williams star in this hilarious romantic comedy about a charmingly family forced to put on airs of getting along to avoid a fiasco of embarrassment.
"It brings together a bunch of people who have unresolved issues," explains Sarandon.
"This is a dysfunctional family – everybody has a little something they've got to figure out," adds Grace, who jokes about the top-notch cast, "Everyone's got an Academy Award but me. Four Academy Award winners in front of me."
De Niro and Keaton play Don and Ellie Griffin, a long-divorced couple who, to the amusement of their adult children and friends, must play the happy couple for the sake of their adopted son's wedding after his ultra-conservative biological mother unexpectedly decides 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.
