Hot Tub Time Machine (2010)

"Hot Tub Time Machine" is the raunchy sci-fi comedy about four friends who get more than they bargained for when a boozy weekend getaway sends them hurtling back to the 1980s. The time-travel gimmick is really just an excuse for the film to indulge in every crude, nostalgic gag it can find, and buried in that chaos is a single clip worth seeking out. Collette Wolfe features in the one nude scene on record here, a brief but genuine flash of skin amid the film's wall-to-wall raunch. It's not a movie built around nudity, but that one scene earns its place in the archive.
