Sid and Nancy

Sir Gary Oldman wore Sid's real chain necklace in the movie. When doing his research, Sid's mom gave him the necklace to wear during filming.

In one of the early pub scenes, the opening band for the Pistols is supposedly X-Ray Spex, belting out one of their best-known hits: "Oh, Bondage, Up Yours!" However, the lead singer Poly Styrene is depicted as rail thin, with long straight hair and no braces on her teeth; most surprisingly, she is portrayed as being white. In real life, Poly (Marion Eliott) is of Anglo-Somali parentage; and in 1977 she was not model thin, plus she had short curly hair and braces. This is because the group was originally meant to be Siouxsie and the Banshees, but they wouldn't give permission for the use of their songs.
