Frenzy marked several returns for Alfred Hitchcock. First, he was going back to his native England where he had not worked for decades. More significantly, he was filming in the marketplace at Covent Garden, where his father had worked as a green grocer. It was also a return to the basic theme that had informed he best work, that of the innocent man wrongfully accused. The final return was to the top of his form that had seemed to be missing for several years. After two films dabbling with international intrigue, Torn Curtain and Topaz, Frenzy was the sort of more grounded and personal suspense tale at which he had always excelled.
