I compared the 2 recent Star Wars producers/directors: Jon Favreau and JJ Abrams on Wikipedia.
They're the same age.
Abrams dies his hair. Favreau does not.
Abrams was the son of TV producers (hence his TV/movie connections and opportunities).
Favreau was the son of an elementary school teacher and a Special Education teacher and had no TV/movie connections.
It is interesting to compare the quality/nature of their contributions.
Abrams is slick, empty and facile whereas Favreau has heart.
