Laughless film goes on for 2 hrs. 23 min.
Danny Devito once said that a good comedy should be an hour and a half long. Get in, get out, leave the audience wanting more. Shirley Maclaine signed on to do this film without reading the script thinking that Lemmon and Wilder knew what they'd be doing. She ended up being VERY disappointed with the finished product, was surprised she received an Oscar nomination and said the if she'd won, she wouldn't have cared. Shame on you Wilder. Actual nudity would have been less sleazy than all those dirty jokes and innuendoes.
There is no "off" position on the genius switch.
