No Filter: These Actors Were Really Getting Intimate On Film!
Stranger by the Lake (2013)

This French drama shows extremely up-front and personal genital close-ups and explicit scenes. The action centers around a lake that becomes a hook-up spot each summer, drawing gay men for guiltless flings and anonymous encounters. But things take a sinister turn when one of the lake’s frequent visitors witnesses an event they were never meant to see.
Stranger by the Lake was critically acclaimed and earned Alain Guiraudie an award for Best Director. The movie also won the Queer Palm award and has was nominated for many other accolades.
