Visible crew/equipment: When Doctor Zhivago comes home after that trolley ride in which he and Lara pass each other without notice, he enters a glass vestibule in the house. As he opens the glass door, you'll see the reflection of a man's face in it. The reflection bears a close resemblance to David Lean, the film's director.
