Man of Honour
as often happens nowadays when an actor portrays the life of a real living person... but still people complained about how things really happened and how realistic everything wasn't.
That's a bit different to Freddie playing Bohemian Rhapsody before they had made the first album or in 1980 Brian May writing We Will Rock You when it had already been a hit in 1977
What's the Runaways film called, I still have all their albums and trying to get my new band to do Cherry Bomb?
