I'm certain David Lynch has some form of autism (film-maker, creator of Eraserhead, Blue Velvet, Twin Peaks etc.) his films, especially Eraserhead, have strong autistic themes. Lynch seems to be fixated on many things, including coffee and cherry pie, a motif which runs throughout his work. His dialogue is very black and white, and his directing seems very surreal and detached from reality. Especially Jack Nance's character 'Henry' in Eraserhead. 'Henry' is very confused and does not understand the world around him, he lives in a bleak industrial landscape full of loud noises, sensory overloads and confusing images.
On a more personal note Lynch is of Irish descent, like myself- I know this has nothing to do with autism but still, I'm proud
I am a film maker and script writer, Lynch has had a strong impact on my work
I have written a screenplay of my own which is currently being made into a full length movie
(i am also producing said movie!)
