Just watched "F for Fake" (Orson Welles, 1973), a documentary of sorts about the great art forger Elmyr de Hory who was able to imitate the style of many of his contemporaries to perfection (Modigliani, Matisse, etc.), fooling the painters themselves!
At one point in the movie his biographer says
> I think Elmyr's problem for years and the reason why he could not succeed as a painter in his own right was that the type of life he led prohibited him from having a personal vision.
Elmyr had great skill, greater than anyone alive perhaps, but he had nothing to say.
