Other mistake: At the end just as Carter is about to be shot, he is facing the sea as he goes to throw his gun away. At this point the gunman fires and hits Carter square in the forehead. The position of the gunman is shown as being behind Carter and to his right (this is seen when the gunman lines up to take aim). Even though Carter leans back as he throws his gun away, he would have been hit somewhere on the right side of his head or temple at best.
Trivia: John "Biffo" Bindon (played Sid Fletcher) had numerous roles during the '60s-'70s as the gangster-type. In real-life he had a violent temper, provoked pub fights and ran a protection racket. It's been suggested that he was known to associate with organised crime leaders the Kray twins and the Richardson Gang, but the extent of his involvement in the English underworld has never really been proven. In 1968 he was awarded the Queen's Award for Bravery (a police bravery medal) for rescuing a drowning man by diving off the Putney Bridge into the River Thames. Some have said that it was Bindon who pushed the man off the bridge but was forced to rescue him when a policeman showed up. By 1971 Bindon went into organising security, which had unfortunate results when hired to be security co-ordinator for Led Zeppelin, during their U.S. concert tour. Then in 1978, Bindon was in a knife fight with London gangster John Darke, which resulted in Darke's death, and by 1979 was on trial where the prosecution claimed it was a contract killing. Defence argued that Darke's death was in self defence (there were allegations that while awaiting trial Bindon bragged to a cellmate that he was a hitman). Though Bindon was acquitted of Darke's murder, his reputation was badly damaged and he became reclusive in the 1980s, before his death in October '93, of AIDS.
Trivia: One of the most memorable things about Get Carter is its use of locations in and around Newcastle. (Indeed, director Mike Hodges even rewrote the script at some points to make use of the locations he'd found.) But what is not so widely known is that the book the film is based on - "Jack's Return Home" by Ted Lewis - was not set in Newcastle at all. It was set in Doncaster.
Eric: So, what're you doing then? On your holidays?
Jack Carter: No, I'm visiting relatives.
Eric: Oh, that's nice.
Jack Carter: It would be... if they were still living.
Edna: What's that gun doing in your room? Suppose I phone the police, told them there's a bloke in my hotel... who's planning to shoot somebody?
Jack Carter: You wouldn't do that.
Edna: How do you know I wouldn't?
Jack Carter: 'Cause I know you wear purple underwear.
Edna: What's that supposed to mean?
Jack Carter: Think about it.
Question: Why does Jack insist that his pint of bitter be in a THIN glass? I've tried doing some Google research on the question and haven't come up with a satisfactory answer. One person says it's a Northerners vs Southerners custom, one says it's in case he needs to use the glass as a weapon, another says he's just being a jerk to the barman as he'd already started to pull it, and a fourth says it's just because that's how Carter ordered it in the novel. Nobody seems to know for certain, though. I'm hoping that maybe someone's seen an interview with Michael Caine or Ted Lewis and has the real answer.Captain Defenestrator
