People have worshipped artists since time immemorial. They help us see the world in a different way. They are the 'unacknowledged legislators of the world' as Shelley put it.
All the great ones have passed except Elvis. Did Brando ever meet Elvis? "On The Water front" is my favorite. Every actor did their best to over act in that film. "One eyed Jacks" is seldom screened but definitely a good film though a little long.
