Character mistake: Austin is supposed to be the archetypal Swinging Sixties Londoner yet he refers to his car as a Shaguar, a pun on 'Jaguar', pronouncing it 'Shag-war'. A native of this green and pleasant land would pronounce it 'Shag-u-ar', three syllables, not two, based on our pronunciation of the car manufacturer's name: Jag-u-ar. He also refers to a truck - a 'lorry' - as a "law-ree." We call them "lurries."
Character mistake: In the Liverpool match the commentator says that Liverpool could win their 19th title, in the 1988-89 season Liverpool had 17 titles, and won their 18th title the year after in the 1989-90 season.
Character mistake: Debbie is doing an "All 80s weekend" on her radio show, and the film's soundtrack is based on exactly the same idea. Debbie plays 'Rudie Can't Fail' by The Clash. This is from the London Calling album, which was released right at the end on 1979 in most countries. The song was never released as a single in any year, so it's definitely a 70s song. What's interesting abut this mistake is that the soundtrack was selected by former Clash lead singer Joe Strummer.
Character mistake: When Dana Appleton objects to Fletcher badgering Kenneth Falk, the judge overrules because Falk is Fletcher's witness. You still aren't allowed to badger your own witness in a trial, which the judge should certainly know.
Character mistake: When they are preparing to film the "Albanian Girl" fleeing the war the girl with the clip board refers to the actress playing the "Albanian Girl" (Kirsten Dunst) by her real name, Kirsten rather than her character name Tracy.
Character mistake: In the opening scene where Olek Krupa is looking at flight departures at San Francisco Airport, you can briefly see two entries that say "San Frnsicso." (00:05:30)
Character mistake: Bentley mistakenly calls Melissa, the kidnapped sister of Ozzie "Gabby", which is the name of her friend.
Character mistake: When Alison is stalling Tanley from entering the bedroom where Haru is escaping being discovered, Tanley refers to Alison as "Angela darling." (00:41:33)
Suggested correction: He says "Oh, aren't you a darling."
