Vintage sci fi movie about a group of people

Question

While searching for less known sci fi movies online I run into a movie, saw few screenshots but can't remember the name of the movie now. Here's what I know:

1. The movie was roughly called something like "The charm of Bourgeoise" or the "The wonderful world of Bourgeoise something".

2. I remember a scene where a group of people were siting by the table and then they found themselves on a theater stage, the curtain lifts up and they see an audience looking at them followed by a group of people storming the stage with guns.

3. The movie is in color.

   What is this movie called?

Answer 1

This is The Discreet Charm of the Bourgeoisie by the director Luis Buñuel, who did a number of surrealist films of this kind--a trailer featuring the scene you're remembering in #2 can be seen here.
