Beau is Afraid was the last one I recall. I think it was mostly the latter half of the movie where I started to get a bit confused and needed the ending explained to me.
What movies made you look up some kind of explanation afterwards? I feel like I have done it several times in the past for more surreal movies but can’t think of any other examples.
It can also be a TV show.
Kubrick actually fought against including an intermission. It was the norm at the time to pause a movie halfway in, raise the house lights, and let everyone piss and get a snack.
The compromise was that the house lights would stay down and the movie would keep running showing the intermission card, with the music that he had composed for it.
I can see from the filmmaker’s perspective but given it’s basically unheard of these days it felt cool and novel. Pretty sure the screening I went to did just what you described
