There is a movie; that is what I mainly remember includes painting the Sistine Chapel, a sort of '50s-60s movie. Maybe Kirk Douglas is in it.
I am not sure if the movie is about some other subject or about Michaelangelo.
The Agony and the Extacy - Charlton Heston
The movie is "The Agony and the Ecstasy," and it stars Charlie Heston. But read the book instead. It's by Irving Stone and it is a fascinating portrayal of everyday life in Rome and Florence 500 years ago.
