Weirdest movie ever?

So many of them. One that's been haunting me lately is a slice of avant-garde from '68 called "The Swimmer." Burt Lancaster plays the titular main character, clad, from start to finish, only in tight swim briefs. It starts out as a cocktail hour frolic -- even jet set age icon Joan Rivers (giving the viewer the chance to see her before she submitted herself to a thousand facelifts) makes an appearance -- before descending into Lynchian depths of surrealism. Movies that start as one thing and then become something else entirely often flounder. For example: "Hancock". "The Swimmer," on the other hand, is an example of a film pulling off this difficult trick with ease.

It's recommended for those who want a really strange experience.
