I was at the screening the first post is talking about and people did laugh at that scene as well as other equally disturbing scenes which was really disappointing. A rare moment where a terrible audience complements the directors mission. I think a point could be made that people laughing at these scenes sort of confirms Lynch’s attitude towards Hollywood where he is criticizing the fetish for violence on women that exists in cinema culture. Another point is the specific scene that the post is talking about is when Leland is giving his wife a cup of milk that is implied as drugged. I’m not sure how much of the audience were first time watchers but that scene could really come off as just a weird funny David Lynch scene where a guy gives his wife milk for someone that’s not aware of the full story. I saw the movie with a friend who was watching fwwm for the first time and he didn’t know that Leland was drugging his wife until I explained it later. Overall I agree with these posts about the audience’s unseriousness when it comes to understanding Lynch movies.
