It has been dubbed The Avengers In Cardigans - no thanks to the multiple odd-coloured woollies worn by the cast of The Imitation Game as part of their recreation of Alan Turing's life.
Keira Knightley, face of Chanel, long-running star of the Pirates Of The Caribbean franchise and generic Hollywood A-lister, wanted to make sure she got the ugliest knit of all.
In fact, as director Morten Tyldum recalls, the actress had agreed to take on the part only if he promised "not to make her beautiful".
But "my face is always my face", the English actress says with the hint of a pursed lip turning into a sigh. "Whether people think it's too glamorous or not... that's what it is."
Knightley, 29, plays real-life mathematician Joan Clarke in the film co-starring Benedict Cumberbatch. As the almost-wife of Benedict's Turing, she plays the inspiration to the inventor of the modern computer and also comforter to the cryptologist extraordinaire who cracked the German Enigma code during World War II.
In the film - as in real life - Clarke had agreed to marry Turing even though she knew he was gay.
"I think people do choose companionship over romance," Knightley muses about her character.
"Particularly for that time period, when married women were giving up everything else and being chained to a kitchen sink.
"I could see her going for that for the friendship and the work and the chance to do what she wanted to. I could see how she could make it work."
What resonated in the actress, indeed, was this spark in a woman who wanted to claim her rightful place in the world of men.
