Christa Campbell joins ensemble indie comedy
Christa Campbell has been joined the indie comedy The Big Wedding, starring Robert De Niro, Katherine Heigl, Robin Williams, Amanda Seyfried, Susan Sarandon, Diane Keaton and Topher Grace.

Justin Zackham is directing the film in which Robert De Niro and Diane Keaton play a couple who pretend they're still married for the sake of their children, and realize it isn't an easy act to keep up.

Christa Campbell's character works in a hospital and attends to Katherine Heigl's character.

Production began Monday in Connecticut.
