A movie that captured one aspect of 'the artist' was based on a book by Joyce Cary: "The Horse's Mouth". I think it is my favourite movie of all time. Alec Guinness is the character, Mr Jimson, a name alluding to the weed which can be deadly. The portrayal of an artist driven by the need to create his art is a tremendous piece of acting by a tremendous actor. It does indeed touch on one facet of 'the artist'.
