There have been a number of movies (both fiction and non-fiction) made with real-life armless women.
The pioneering one has to be Freaks www.imdb.com/title/tt0022913/, from 1932. This featured, not one, but two women born without arms: Frances O’Connor, who appears in several scenes, and Martha Morris, who appears in just one.
Being Different www.imdb.com/title/tt0131963/ from 1981 is a documentary featuring many physically-unusual people. Towards the end, we see Louise Capps, born without arms, go about her daily life, and talk about herself.
A more recent production is Fur: An Imaginary Portrait Of Diane Arbus www.imdb.com/title/tt0422295/ from 2006. This is a fictional story, loosely based around real-life photographer Diane Arbus, who made a career out of taking pictures of the unusual. This includes a couple of scenes with a character played by real-life armless artist Mary Duffy.
And then there is the Chinese-language film Invisible Wings www.imdb.com/title/tt1573843/, starring Lei Qing-Yao, and loosely based on her real life: rather than being born without arms, she lost them in an electrical accident as a child. This has been dubbed into Telugu, but not as far as I know into English.
Can anyone think of any others?
