Trivia: John Lydon aka Johnny Rotten despises this film. He accused it of glamorizing the squalor of Sid and Nancy's life and making heroin addiction seem cool. He has referred to the film as "a f*ck*ng fantasy." Amongst his more scathing quotes : "To me this movie is the lowest form of life. I honestly believe that it celebrates heroin addiction. It definitely glorifies it at the end when that stupid taxi drives off into the sky." "I don't think they ever had the intent to research properly in order to make a seriously accurate movie. It was all just for money, wasn't it? To humiliate somebody's life like that - and very successfully - was very annoying to me." "I went to see it and was utterly appalled. I told [director] Alex Cox, which was the first time I met him, that he should be shot, and he was quite lucky I didn't shoot him. I still hold him in the lowest light. Will the real Sid please stand up?" "As for how I was portrayed... it was so off and ridiculous. It was absurd. Champagne and baked beans for breakfast? Sorry. I don't drink champagne. He didn't even speak like me. He had a Scouse accent." (Lydon is a Londoner.) Alex Cox later admitted that many of Lydon's criticisms of the film were correct and he should have shown the squalor and ugliness of Sid and Nancy's life in a far more realistic manner.
Trivia: In the movie, when we first see Lady Jane Grey, we see a painting of Helena Bonham Carter as Jane. The portrait this was based on was long believed to be the only known portrait of Lady Jane but is now reclassified as Henry VIII's last wife, Catherine Parr. It is in the National Portrait Gallery, London, England.
