When Ellie is packing to go to London, the LP discs fill up to almost the height of the open suitcase but in the next shot, it looks half empty.
When John is talking to Ellie at the pub the poured beers have shifting amounts of foam.
When Sandie is singing "Downtown" at the audition (around the 38-minute mark), she sings "When you've got troubles, all the noise and the hurry seems to help, I know," while the true line (which actually rhymes!) is "when you've got worries, all the noise and the hurry...." Also, she ends the song with the repeated line, "Everyone's waiting for you," instead of "Everything's."
Not a mistake, she is changing the lyrics deliberately.

When Sandie and Jack go into the restroom to kiss, you can briefly see Sandie's reflection in the mirror, when it should be Ellie.
Large survey classes, like the one Ellie arrives at late, generally don't take attendance orally because calling roll for dozens of students would take up an inordinate amount of time which could be used for instruction.
In the music credits at the end, the song Eloise is shown as being written and performed by Barry Ryan. Barry Ryan did perform the song but it was written by his brother Paul Ryan.
One of the musical acts featured in the Rialto Club was Sandie Shaw's "Puppet on a String". Multiple references, such as advertisements for the release of Operación trueno (1965), set the movie in 1965, however "Puppet on a String" was the 1967 winner of the Eurovision song contest and was released 7 March 1967 just one month prior to the contest.
When Eloise goes back to the 60's for the first time Thunderball is shown to be premiering at the cinema. On the right of shot a film called Darling is in the 'coming soon' list. While both films were released in 1965, Darling actually premiered 3 months earlier than Thunderball.
When Ellie plays 'You're My World' in her bedroom at the start of the film, she uses the reissue EMI EP from 1977 rather than the black Parlophone 45 version from 1964.
Eloise asks the librarian for information on missing persons for the entire 1960's, but she had an obvious reference to narrow her search - Thunderball (1965) was released in the UK on December 29, 1965 meaning this was early 1966 at the earliest.
While the ambulance crew treats Ellie and her friend for their wounds and smoke inhalation, no one mentions the poisoning at all.
The ambulance crew did well in giving oxygen to Ellie in a Non Rebreathable Mask (fitted with a plastic bag to concentrate the oxygen) as she is at risk of having being intoxicated by the fumes. But then they remove the mask that is perfectly effective to fit her with a "bag valve mask" (aka Ambu) and start ventilating her (the paramedic is pushing on the bag) when she is actually conscious and breathing by herself (which could only force air into her stomach and make her vomit in her lungs).
