Luis Bunuel's Movie Gil Was Talking About

"The Exterminating Angel"

Just like Marty McFly wrote Johnny B. Goode, Gil wrote The Exterminating Angel: https://en.wikipedia.org/wiki/The_Exterminating_Angel_(film)

By morning it is apparent that, for some inexplicable reason, they are psychologically, but not physically, trapped in the music room. Unable to leave, the guests consume what little water and food is left from the previous night's party. Days pass, and their plight intensifies; they become quarrelsome, hostile, and hysterical - only Dr. Carlos Conde, applying logic and reason, manages to keep his cool and guide the guests through the ordeal. One of the guests, the elderly Sergio Russell, dies, and his body is placed in a large cupboard. Much later in the film, Béatriz and Eduardo, a young couple about to be married, lock themselves in a closet and commit suicide.

Buñuel's reaction to Gil's suggestion is priceless...basically saying, "WTF? That doesn't make a lick of sense." I think Buñuel would have loved that irony.
