Welcome, or No Trespassing

Welcome, or No Trespassing is a 1964 Soviet comedy film directed by Elem Klimov. It was capitalizing on the formal restrictions that children face during their vacation in a Young Pioneer camp. Most of the cast are children, while the protagonist is the director Dynin, played by Yevgeniy Yevstigneyev. The film was selected to be screened in the Cannes Classics section of the 2015 Cannes Film Festival. Both Soviet censors and modern critics characterize it as a clandestine political satire, albeit for different reasons.
