Actually, JT’s acting roles started drying up in the period after his dance with Diana, and that’s when he took up flying, with a view to becoming a professional pilot. He was then cast with fellow Scientologist, Kirstie Ally, in Look Who’s Talking, which was a surprise hit, and kickstarted his career. Then became a legendary cool dude with Pulp Fiction. I imagine Harry is actually quite jealous of the iconic moment between Travolta and Diana, Oedipal mess that he is.
