Another interesting film I’ve come across by happy accident: Valerie a týden divů/Valerie and Her Week of Wonders from 1970 is Czechoslovak surrealist fantasy horror film directed by Jaromil Jireš, based on the 1935 novel of the same name by Vítězslav Nezval. Seen the film described as “a surreal polychrome coming-of-age vampire costume drama”.
