MisterMatt - I saw Hoy No Me Puedo Levantar twice while I studied abroad in Madrid. What blew my mind was that the cast was able to do a 4 hour 20 minute dance-heavy rock musical back to back (at 4pm and 9pm). Amazing stamina.
Kristina från Duvemåla. It was around 4 hours with intermission i think. It will be shortened with an hour for Broadway though. I read that someone who participated in the workshop and who was very positive overall, had called the journey to the states "a long one", so i guess that's what they will cut.

Mary Poppins was pretty long when it first opened... The West End show "Acorn Antiques" was OVER LONG - about 3 or 3 1/4 hours (groans). The longest PLAY I've ever seen is Who's Afraid of Virginia Woolf...
I went to a community theatre performance of Amadeus once ... it had to be around three hours and it felt like it would never end. My old high school did Kiss Me Kate once and, though it was probably the best show they've pulled off in the four years I went there, it dragged itself out. I don't remember the final time but it was quite long. I did like it though so it wasn't too bad.
A production of Gypsy I saw recently...I swear the scene changes took five minutes EACH. It ran for more than 3 1/2 hours. It was a shame, as Mama Rose was fabulous. But it was dreadful sitting through those scene changes...
