Horror Hunks: Alec Owen, Paul Prado, Ben Gigli, Brandon White, Joey Scoma, John Francis Daley, K.C. Kastaros, Greg Sestero, Jimmy Wong, Mark Lorenz, Michael Rousselet & Jon Brence in Dude Bro Party Massacre III (2015)

The horror satire Dude Bro Party Massacre III follows Brent (played by Alec Owen), a college student who joins the school's notorious fraternity in an effort to solve his twin brother Brock's murder, after Brock "coincidentally" survived two previous serial killing sprees on fraternity row, by murdering the villainous Motherface and later her daughter who took on the mantle of her crazed mother. Brent soon discovers that a third Motherface is on the loose, while bonding with his new frat bros who fall to the killer one-by-one. Given the film's satirical focus on college-set horror tropes, the guys all find themselves in various states of undress while evading the killer. Alec even shows rear nudity. There's also partial rear nudity from Jimmy Wong. Alec's co-stars Paul Prado, Ben Gigli, Joey Scoma, Greg Sestero, Mark Lorenz, Michael Rousselet & Jon Brence were all shirtless. Brandon White was shirtless for all of his scenes, as Brent transformed into Brotherface after becoming possessed by his fallen frat bros to face the killer. John Francis Daley & K.C. Kastaros were also shirtless for their brief cameos early in the film.
