The film cast includes four Oscar winners: Robert De Niro, Diane Keaton, Susan Sarandon, and Robin Williams; and one Oscar nominee: Amanda Seyfried.
In this movie, Robin Williams's character quotes Oscar Wilde's "Marriage is the triumph of imagination over intelligence. Second marriage is the triumph of hope over experience."
This is the second time Robin Williams has played a priest marrying a couple. The first being Lizenz zum Heiraten (2007).
In reference to the scene where her character jumps into a lake naked, Ana Ayora said: "There was definitely a little bit of anxiousness, but that was Nuria. Nuria wouldn't hesitate, so I didn't hesitate."
Justin Zackham asked Carlos Bakery (of Cake Boss fame) to provide three exact replicas of the wedding cake for use during filming. One was made of Styrofoam, but the other two were real.
