Horror Hunks: Chris Conroy & Jonny Orsini in Beneath (2013)

Beneath is a creature feature centered on a group of high schoolers who enjoy an excursion into the woods. When they head out on the lake in a rowboat, they cross paths with a man-eating fish putting their lives in instant peril. Chris Conroy plays one of the teens, Matt, who gets out of his clothes to go for a swim, before the group realizes what's in the water. He spends much of the film in skimpy swim trunks. Jonny Orsini also gets shirtless for his role as Simon. When the group gets desperate, Matt & Simon get into a fight where Matt tears Simon's shirt off, before they both end up in the water. Jonny spends the rest of the film shirtless.
