Thomas McDonell is set to star in the indie “I’m Obsessed With You,” based on a play by Genevieve Adams.

Jon Goracy will direct with Adams penning the script. Goracy and Adams will also produce.

Story is set at Darby College, days before graduation, where four best friends and members of a notoriously eccentric improv group look to the future.

Shooting will take place in New York City and the Hamptons.

Besides 2011’s “Prom,” McDonell will be seen this fall in the CW show “The Hundred,” which McDonell will begin shooting after he finishes production on “I’m Obsessed With You.” He is repped by WME and Frankfurt Kurnit Klein & Selz.
