Trivia / This Is Where I Leave You

• Casting Gag: In the book, Judd recalls seeing his mother using one of Jane Fonda's exercise videos (and saying she was prettier too). In the film, the mother is played by Jane Fonda.
• Screwed by the Lawyers: The family in the book was called Foxman. They're changed to Altman, because the former couldn't be cleared legally.
• What Could Have Been: Early casting choices included Goldie Hawn, Zac Efron, Leslie Mann, Malin Åkerman and Jason Sudekis. This was when Adam Shankman was set to direct.
