Jackson Gallagher, Shane Nagle & Damon Gameau in Patrick: Evil Awakens (2014)

In this remake of the 1978 Australian horror film, Patrick, the title role is played by Jackson Gallagher. The hunky actor (and current Home & Away star) appears shirtless for just about the entire film, except for a few flashbacks. Patrick is a comatose patient, with a dark past, who is the subject of some medical experimentation and seems to possess telekinetic abilities. The previously-mentioned flashbacks also include some brief rear nudity from Jackson. His co-star Shane Nagle also appears in those flashbacks with a bit of rear nudity as well, as his unnamed character is bathing along wtih Patrick's mother. Damon Gameau also stars in the film and has a brief shirtless moment at the end of the film.
