Horror Hunks Classics: Tim Matheson in Impulse (1984)

Tim Matheson got a rare rear nude scene for his horror debut in Impulse. The film follows small town residents who face increasingly bizarre and violent behavior from their neighbors after an earthquake hits the town. Tim's character Stuart finds himself romancing leading lady Jennifer, before they get dragged into the local menacing attacks. After getting a massage and hearing a strange noise coming from the hallway, Stuart leaves the bed behind, throwing on a towel to cover his bare butt. He was also shirtless for the scene.
