Knock for Knock (1976)

Este é o segundo filme dirigido por Hitchcock, mas, que se saiba, não resta nenhuma cópia. Em Kentucky, Beatrice (Nita Naldi) é uma professora que recusa as abordagens do vilão Pettigrew (Bernhard Goetzke). Como vingança, ele inventa que ela teria molestado Edward (John Hamilton), um jovem retardado. Temendo a ira dos moradores da cidade, Beatrice se esconde nas montanhas, onde é acolhida pelo eremita Fear O God (Malcom Keen). Ele propõe um casamento de aparências para acalmar os ânimos das pessoas, mas os dois se afeiçoam e a união se torna real. Mas Pettigrew, ainda com ciúmes e raiva, arma novas mentiras para prejudicar os dois, dando continuidade a uma trama de intrigas, injustiças e reviravoltas. Apesar da história se passar nos Estados Unidos, o filme foi rodado nas montanhas da Áustria. Filme mudo.

Second attempt to create a feature film out of the 200,000-plus feet of film which Soviet film-maker Sergei Eisenstein shot during 1931-32 in Mexico for American socialist author Upton Sinclair, his wife and a small company of investors. The projected film, to be called "Que Viva Mexico", was never completed due to exhaustion of funds and Stalin's demand that Eisenstein return to the USSR (he had been absent since 1929). The first attempt at editing the footage, in the USA, resulted in "Thunder Over Mexico", released in 1934. In 1940, Marie Seton, from the UK, acquired some of the footage from the Sinclairs in an attempt to make a better cutting according to Eisenstein's skeletal outline for the proposed film. This film has apparently been lost.

The circus provides the backdrop for this melodrama that chronicles the lives of four children raised within the big top. Film historian and collector William K. Everson stated that the only surviving print was lost by actress Mary Duncan who had borrowed it from Fox Studios. In the December 1974 issue of "Films in Review," he explained that Mary Duncan, one of the film's stars, wanted it to show to a group of friends in Florida. The star was aware that it was a dangerous nitrate print and assumed that Fox had others. She threw the only copy in the ocean, a mistake characterized by Everson as "a monumental blunder to rank with Balaclava, Sarajevo, and the Fall of Babylon as one of history's blackest moments."
