The first time we see Elton John in Rocketman, he's wearing a spangly red devil costume with sharp horns and enormous wings. It's one of the many glorious, glittery things we see him wear in the movie, although on this occasion, he isn't dressed for a concert. It's around 1990, and Elton, played by Taron Egerton, is attending a group therapy session. He may be one of the world's most successful rock stars, but he's also being eaten alive by sex addiction and substance abuse, and also by feelings of abandonment that go back to his childhood.
