The upcoming comedy-drama stars writer-director Josh Radnor as a thirtysomething New Yorker who returns to his alma mater and gets drawn into a quasi-romantic affair with a 19-year-old college student (Olsen).
Zac Efron, Richard Jenkins and Allison Janney round out the film's cast.
Liberal Arts played at this year's Sundance Film Festival, and later transferred to the inaugural Sundance London festival.
