I have never seen the movie but had the pleasure of recently watching a beautiful full-length play written by Leonard Nimoy and a stunning performance by one man named Jim Jarrett. He does a one man performance portraying both Theo and Vincent and the story takes place actually after Vincent's death. Taken from the Book of Letters To Theo.
Quite exciting to see the transformation within this fanastic young man. See him at

He is a traveling one man actor and is a great and very nice young man.
