I was watching the movie To Sir With Love and in some of the scenes I thought I saw a young woman who looked Indian or South Asian; in particular, the school dance at the end when Sidney Poitier's character Thackeray, the out of work engineer who takes a job as a teacher in London's East End, dances with one of his students. If you watch this preview to the end, you can catch a quick glimpse of her.
Some of the shots at the dance 'cut' to a beautiful woman with cropped, bobbed black hair and smooth skin. She is in complete mod costume, dressed in black and white with a shimmery pale mouth, as is the fashion, and is doe-eyed and wearing enormous earrings that move with her. I searched the credits and found that one of the cast members is Chitra Neogy. She may be the one in center-back in this photo.
I tried to find out more about her: someone named Chitra Neogy had a sitar-tinged single in the late 60s called The Perfumed Garden. She has a limited filmography, and the most recent work I could find is a film entitled A Journey Within a Journey. It's odd: I've seen To Sir, With Love a million times, I love it because of the Swinging Sixties London fashions, the Lulu song and of course Sidney Poitier (who really should have been the next Cary Grant, he's the only actor I can think of who carried himself with the same assurance and control, whatever happened?) and yet I never really noticed her. I wonder if the Sepia Mutiny guys do retro desi sightings?
