The movie follows a 35-year-old who still wants to live like a college kid, but must come to terms with his age and budding responsibilities. Olsen plays a 19-year-old student who falls for Radnor's character and bonds with him over their love of music and literature. Age ultimately comes between them as they yearn to make the relationship work.
Radnor, who recently made his directorial debut on the film HappyThankYouMorePlease, also wrote the script that is scheduled to prep this spring.
Olsen, the younger sister of Mary-Kate and Ashley Olsen, recently created buzz for Martha Marcy May Marlene, which debuted at the Sundance Film Festival. The 22-year-old actress currently is filming Red Lights opposite Robert De Niro, Sigourney Weaver and Cillian Murphy.
