auteur

auteur A creative artist, especially a film director, seen as having a specific, recognisable artistic vision, and who is seen as the single or preeminent ‘author’ of his works.
1974, William Bender, "Call to vespers", Time, 11 Feb 1974:

The libretto was a piece of hack work from a Parisian scenario factory run by an enterprising auteur of sorts named Eugene Scribe.

Since Mr Luhrmann first tackled the opera, he has entered the select circle of celebrity directors on the basis of only three films, including “Moulin Rouge”. And his “La Bohème”—designed by Mrs Luhrmann, Catherine Martin, a double Oscar-winner for “Moulin Rouge”—is avowedly the work of an auteur.

If a widely respected auteur such as Martin Scorsese, Allen or Malick has given you the stamp of approval, you might not live fast or die young, but you'll leave a good-looking legacy.
