Corrected entry: As the challengers are getting ready for the college dash, the starter incorrectly says "Now remember, on the first strike of 12." He should have said "on the first strike of 1" because they start running on the strike of 1 and must finish before the clock strikes 12.
Corrected entry: The dress Sybill wears to her first date with Harold is far, far too low cut for 1912. The neckline goes below the lower curve of her breasts. In 1912, forget it. This isn't a character choice - wearing a dress like that in Edwardian London would be like turning up naked nowadays. Couldn't happen, didn't happen.
Corrected entry: The parade of the participating nations in the opening ceremony is wrong. The countries march in alphabetical order according to each countries native tongue (ie. regardless of host country's language). Therefore 'Great Britain' would go before 'United States'.
Corrected entry: When Harold and his friends are watching "The Mikado" in the theatre, there is an illuminated exit sign behind them in the balcony. I don't think these were around right after World War I.
Corrected entry: This 'college dash' that Abrahams impresses Cambridge University by completing - something's not right. The challenge is to get around the courtyard in the time it takes the clock to strike midday. The big deal is that this challenge is supposed to have been around for almost seven centuries and no one has ever completed it successfully. That means that the college dash originated in the early 13th century. There couldn't have been a clock like the one used to time the dash back in the 1200's.
Corrected entry: When the committee is discussing what to do about Eric not running on Sunday, one members calls the Prince of Wales, "David". Unfortunately, that's the actor's name, not the Prince's.
