Sinfonía otoñal

This was the earliest American film to feature extensive location work in Italy involving the principal actors. Whilst filming, Joseph Cotten was invited to lunch by his old friend Orson Welles, who confided that he had also invited a couple of Italian businessmen whom he wanted to invest in his film version of "Othello". The presence of a film star would, Welles hoped, influence them to put up some money. Also in the restaurant was Sir Winston Churchill, whom Welles hailed most affectionately as he walked past. He later admitted to Cotten that he and Churchill had never previously met, but that he was hoping that this, too, would impress the Italians. His strategies worked; they agreed over lunch to help finance Welles's film, and Cotten and his co-star Joan Fontaine even played uncredited cameos in "Othello" whilst they were still filming "September Affair".

Right after David Lawrence Jr says to Marianne 'Manina' Stuart, "We weren't sure that Madame Salvatini would forward it to him.", the street scene out the window behind them skips, revealing a projected film loop starting over again.
