The important thing, once you get 'em laughing, is to keep 'em laughing until you're through. With a 90-minute feature, you've got to stop the laughter and then pick it up again, which is tough.
You can't make people laugh for more than half an hour and be consistent.
The greatest comedies that were made by anybody were made in two reels; I don't care who it was.
