Play It As It Lays (1972)
After the conversation about films, an overhead shot of the freeway system is shown for an extended period. This scene clearly mimics the famous overhead freeway shot in Play It As It Lays.
Play It As It Lays is advertised on a marquee with Day of the Locust.
The title of Joan Didion's famous book and/or the film adaptation by Frank Perry are referenced in a line by Stafford Weiss. Didion's book (and screenplay) has plot and character similarities to 'Maps to the Stars'(2014).
