Young Adam (2003)

"Young Adam" is a 2003 British drama set on the Scottish canals, following a drifter whose past comes apart as he works a barge and gets tangled in the lives of the people around him. Emily Mortimer plays one of the women drawn into his orbit, and the film doesn't cut away from the physical side of that story. The archive holds 4 scenes of her nude and having sex on screen, shot with the same flat, unglamorous look as the rest of the picture.
