Liberato will play the younger version of Monaghan’s character Amanda in the tale of two former high school sweethearts who reunite 20 years later in their hometown for the funeral of an old friend. The novel adaptation is directed by Michael Hoffman (The Last Station) from a script by J. Mills Goodloe, Will Fetters, and Hoffman. This is the third Sparks pic at Relativity after last year’s Safe Haven and 2010’s Dear John. Liberato’s upcoming projects include If I Stay and Dear Eleanor. She’s repped by CAA and Management 360.
