That was when time began

Errol Flynn & Mary Stuart
In "The Adventures of Don Juan" (1948)

Don Juan: Beloved, no power on Earth could've kept me from you. In all the world there's been but one image in my heart, one vision before my eyes...

Catherine: Yes, yes, go on...

Don Juan: I have loved you since the beginning of time.

Catherine: But you only met me yesterday...

Don Juan: Why, that was when time began!
