Alfred Hitchcock začínal ještě v době němých filmů.
Ve dvou z nich hrála česká herečka Anny Ondra.
A jeden z nich Hitchcock stihl upravit/přetočit do "mluvené" verze a v britských kinech pak šly obě.

Ultimately, two versions of the film would be released to British cinemas — one with sound and one without.
