One Hour Photo (2002)

One of comedian Robin Williams’s unexpected but enduring talents is his ability (and willingness) to portray a creepy, sexually maladjusted, homicidal loner. In One Hour Photo(2002), Williams is alternately heart-wrenching and stomach-turning as Sy Parrish, a former fat kid who never had any friends. Sy has slithered into middle age with only the most rudimentary of social skills and a career arc that has peaked as a film developer at an instant-photo stand. With nothing in his life but a drab downtown apartment, lonely and looney Sy naturally projects himself into the family scenes in the photos he so meticulously develops. Does Williams’s character cross the line from innocent, slimy obsession to dangerous fixation? The question is "when" not "if."

Luckily, we’re spared any Naa-new-naa-nude moment of Williams in this movie.  Michael Vartan, however, lets the audience see his character develop fully, braving a full frontal second. But be warned, you’ll want to keep at least one hand free for the pause button to catch it.
