While in Knoxville, we watched Rumor Has It (2005,PG-13) (ScreenIt! Review) with the Bells.

From Wikipedia:

The entire movie is told, presumably from the present, as a flashback to events that happened in 1997. It is also, as flashed on the screen at the beginning of the movie, "Based on a true rumor". In the backstory to this movie, Sarah's grandmother, Katharine Richelieu (played by Shirley MacLaine), had an affair with the much younger Beau Burroughs (played by Kevin Costner), forming the inspiration for the affair in The Graduate between Benjamin Braddock and Mrs. Robinson (whose first name, incidentally, was never mentioned in that movie).

I didn't think there was much to it, but it was passable. I give it 3 out of 5.
