James Dean is known the world over, has been since he began acting. His popularity continues now long after his death.

Lady Gaga is much more famous as she is known world wide.
Charlie Chaplin will probably be famous for years to come, whereas Lady Gaga will probably fade into obscurity in a decade. However, at the moment, looking at the demise of old movies, Lady Gaga is probably better known.
