Jacqueline Bisset plays "Jacqueline" (cf. "Two For the Road") in this black & white film directed by Roman Polanski ("Chinatown", "Tess", etc.). Her first speaking and credited role, billed as "Jackie Bisset" (cf. "Casino Royale"). Filmed on Holy Island, off the Northumberland coast.
Polanski considered her for the lead, but gave that role to Françoise Dorleac (Catherine Deneuve's sister). Jacqueline said: I'll never thank him enough, because it's very dangerous to be faced with an important role when you're inexperienced - if you blow it, it could be the end.
All in all, it was a fascinating experience and since it was my first "real" film, I spent every second of my free time - I had lots as it turned out - watching, watching, watching. Polanski directed and I'd sit nearby, learning. [Hello!, #248, 1993.]
Here are her first words on film. (1.5 MB QuickTime Movie)
There is a website devoted to "Cul-de-Sac": Clive's Cul-de-Sac site.
"Cul-de-Sac" was released on video, though it is now out-of-print. I would expect that it would be released on DVD at some point.
