Mortal InstrumentsRobert Sheehan has been set to star opposite Hailee Steinfeld in Dustin Lance Black’s romantic drama The Statistical Probability Of Love At First Sight. Oscar-winner Black wrote and will direct the project. He’ll also exec produce with Bruna Papandrea, Caroline Kaplan and Steve Hutensky producing.

Based on the 2013 YA novel by Jennifer E. Smith, the story follows Hadley (Steinfeld) over a 24-hour period. What first looks like a rotten day as she waits at JFK for a flight to London and her father’s second wedding, brightens up when she meets a young British chap (Sheehan). Turns out they’re seated together on the plane, and sparks fly as they discover that true love is an act of bravery that’s well worth the leap.

The Exchange is handling international sales with CAA on domestic. Production is set to begin later this year. Sheehan, next up in Dean Devlin’s Geostorm, is repped by Gersh and Lisa Richards Agency.
