With a father (Steven Mackintosh) who refuses to hug him and a mother (Bryce Dallas Howard) who makes him feel worthless, Elton was destined to suffer insecurities. These are unlikely to be all that's responsible for his drug and alcohol abuse, but it's a tidy answer for a film like this. (Hopefully Elton fans will learn a little more in his autobiography, due out this year.)
Rocketman is also a cautionary tale of overnight success. After teaming up with lyricist Bernie Taupin (Bell), who could write lyrics as fast as Elton could set them to music, success came quickly - in the UK, the US and worldwide.
There were plenty of people keen to benefit from this success, and Elton doesn't always surround himself with the best people. His volatile relationship with his ex-manager and lover John Reed is a case in point, with Bodyguard's Richard Madden putting in a strong performance a cruel taskmaster.
But what makes Rocketman magic is the music, and the way Elton's songs tell his story. Egerton fully commits to the role of Elton - it's the most charismatic I've seen him on screen – and, although sometimes he's a little karaoke, he is always emotional and dynamic.
If you're a fan of Elton John, you're unlikely to learn anything new but, like the man himself, Rocketman is about entertaining the crowd and on, that basis, he's delivered another hit.
