Mrs. Harris Goes to Paris goofs

Although the film is set in 1957, a pub scene features Chuck Berry's 'Johnny B. Goode', which had not been released until 31 March 1958.

The seating at the greyhound stadium appears distinctly modern — certainly not from the 1940s.

In Mrs Harris the phrase "you go, girl" is used, although that expression did not emerge until the early 2000s.

After arriving in Paris, Mrs Harris walks from the airport into the city, passing a Peugeot 404 parked by the roadside. The 404 wasn't introduced until 1960, while the film is set in 1957 — a detail that connects to the Parisian refuse collectors' strike of that year.

Towards the end of the film there are posters on the wall bearing the heading Royal British Legion. The British Legion didn't gain 'Royal' status until 1971 — 14 years after the period in which the film is set.

Mrs Harris is driven round Paris by Dior model Natasha, who befriended her. Natasha's car is a Renault Caravelle, the name clearly displayed on the front of the vehicle.

The Caravelle name was not used in France until after 1962.

Also, the stereo unit in the car's dashboard looks too modern to be from the 1950s.

Whilst cleaning, Mrs Harris puts on a record, playing "On n'oublie rien" by Juliette Gréco. The film takes place in 1957, yet the song was not released until 1960.

The young RAF officer is wearing the King's Crown above the RAF wings on his left breast. After Elizabeth II became queen in 1952, the RAF wings were thereafter surmounted by the Queen's Crown. By 1957, a young man of this sort would not have held the rank of squadron leader, nor would he have been wearing the King George VI crown on his wings.

When Mrs Harris first settles into bed in her flat, the bedside table is on her right; later, it's on the left.

Mrs Harris is shown dozing on the flight from London to Paris, suggesting the journey was lengthy. Even aboard a piston-engined airliner, the flight would take only about 45 minutes.

While Archie and Ada are chatting on the dance floor, he's holding a half-full pint of beer that suddenly vanishes once they begin to dance.

As the red car is driven through Paris, filming equipment is visible in the vehicle's paintwork.

She spends the greater part of a week having a dress tailored to her figure, yet it can nevertheless be worn by another woman who clearly has different measurements.

Mrs Harris's deceased husband served in the RAF, yet the photograph shows him dressed in army battledress.

Racing greyhounds wear standard colours that correspond to their trap number. The dog in trap six always sports black & white stripes with a red numeral.

When Pamela calls on Ada for help with her dress, she sits down with a cigarette in her hand; it appears she drops it, yet it is still in her hand (the shot seems to have been trimmed and not joined correctly).

It seems unlikely that Mrs Harris would have flown from London to Paris. At the time, air travel was prohibitively expensive, and for someone of her means it would have been far cheaper and more plausible to travel by rail and ferry.

Dior's chief designer at that time, Yves Saint Laurent, does not feature anywhere in the film.
