My regular reminder that 2001: A Space Odyssey was only 2h 23m, and that movie had an intermission at the cinema. Tess of the d'Urbervilles? 18 minutes longer than M:I, and that one had an intermission, too. Ghandi had an intermission, but $DEITY, no human bladder can hold that much so it was kind of required.

Your Marvel movie is approaching 3 hours, and no intermission? Fuck that, I'll watch it at home while your CEO whines that no one goes to the movies anymore.

(Wait a minute, Oppenheimer is three hours long? Sorry, ChrisN, but that's one's getting streamed in my living room, too.)
