Two scenes take place in the apartment shortly before Mary's death. In the first, Blanche takes Jimmy into Jack and Mae's bedroom and seduces him. The second came a few minutes later, after the act has occurred, and both act groggy, as though sex while high gives you a hangover. Both of these scenes were often removed because of regional obscenity laws, but they survive today seemingly intact.
The scene of Hotfinger toking up in the closet at the restaurant, and Mary getting lit by Ralph, were censored from some prints.
The shot of Mary unzipping the back of her dress, plus the close-up dolly-in shot of her lying on the sofa, was censored from some prints.
20th Century Fox DVD release flashes "420" on the screen for a couple of frames when Billy first enters Mae and Jack's apartment. This is in both the black-and-white and colorized versions on the disc.
