My Fair Lady played with an intermission in 70mm in the U.K. I’m surprised if it didn’t have one in the U.S. Even the soundtrack CD has the Intermission music!
I saw The Great Waltz at the London Casino but can remember absolutely nothing about it other than that during the intermission I was wishing Part 2 to hurry up and start so that the torture would soon be over!
I saw The Great Waltz when it opened in Cinerama at the London Casino. I can't say what it was like because all memory of the film seems to have been erased from my brain.
