Hans Richter: Dreams That Money Can Buy (1947)
Hans Richter was an original member of Dada and one of the first avant-garde filmmakers. He started making experimental movies in the early '20s. One of my favourite movies by him is Dreams That Money Can Buy, about a man who sells dreams to people. This of course is just an excuse for Richter and his artist friends - Max Ernst, Doroteha Tanning, Alexander Calder, Man Ray, Marcel Duchamp - to compose a series of loosely connected vignettes displaying their artistic craft. It's funny, poetic, horrifying, baffling, playful, ambiguous, ambitious and daring.
I think anyone who likes unusual cinema will appreciate this film.
This world is a comedy to those that think, a tragedy to those that feel.
