Tenney will play a father trying to reconnect and protect his teenage son, played by Penn Badgley (“Gossip Girl”). Heard plays Badgley’s girlfriend. “Friday Night Lights” actress Adrianne Palicki was in negotiations for Heard’s part, but the dates did not work out.
Sela Ward is already on board as Tenney’s ex-wife, whose soon-to-be husband (Dylan Walsh of “Nip/Tuck”) might have murdered his previous family.
“Stepfather” reteams director Nelson McCormick and writer J.S. Cardone, who worked together in the same capacity on another Screen Gems remake, Prom Night, which opens April 11.
