Relative Values (2000)

Continuity mistake: One of the characters flies from America to England. He takes off in a Pan-Am Boeing Stratocruiser, but lands in a TWA Lockheed Constellation.

Miranda Frayle: I'm absolutely determined that the Countess of Marshwood shall be the longest, and greatest, role I ever played.
Felicity Marshwood: I do hope you won't find it too much of a strain.
Nigel: Mother.
Felicity Marshwood: I do know what I'm talking about. I've played it for years. I find it a good part, but technically rather exhausting.
