A Report on the Party and the Guests Czech O slavnosti a hostech , also known in English as The Party and the Guests is a 1966 Czechoslovak drama film directed by Jan Nmec. It was entered for the 1968 Cannes Film Festival, but the festival was aborted owing to the events of May 1968 in France. The film was banned from 1966 to 1968 for being perceived as an allegory of totalitarian regimes. After a short release during the Prague Spring it was banned again for the next twenty years. In 1974 director Jan Nmec was forced to leave the country.
