Scene from Mystery and Imagination:
Uncle Silas (1968)
More Colour and Black-and-White comparisons. This is from the DVD's image gallery:

Patience Collier as Madame de la Rougierre and Lucy Fleming as Maud Ruthyn - in colour.
This is how they, and more significantly the costumes, looked in black-and-white, with Patience caught off guard!

:

She was just as terrifying in TV's
Who Pays the Ferryman? a decade later and, to a lesser extent,
Endless Night.
This is the nearest equivalent to the colour picture. The old hag, Maud's guardian, has dragged her to her mother's grave:

"Tell me, or I will break your fingers!" - "No, Madame. You're hurting."
The year before, Lucy played Lydia Bennet in a BBC adaptation of
Pride and Prejudice, though
she is probably best known for the Sci-Fi series
Survivors - and as the wife of Simon Williams.
