Per BookPage: “Gruen and her entire family have cameos in the movie. Her big moment comes when Robert Pattinson (as Jacob) brushes past her during a tense scene with a runaway circus animal. “I’m the astonished woman watching an elephant [Rosie] steal produce!” she says.”
And according to The1stdaughter over at There’s A Book, Something Borrowed author, Emily Giffin, will be making a cameo in the new movie based on her book. Ms. Giffin will be sitting on a bench reading a book in one of the scenes with Rachel in it. How appropriate!
Here are a few more movies with author cameos:
Holes by Louis Sachar (Mr. Collingsworth, bald man who receives onion hair tonic from Sam)
Pet Cematary by Stephen King (minister at funeral)
Twilight by Stephanie Meyers (eating at a diner)
The Outsiders by S.E. Hinton (plays the nurse in Dally's room)
