At the airport P.L. Travers is shown at the gates of the fictional British Transcontinental Airways, but the interior of the plane has BOAC (British Overseas Airways Corporation) logos.

Scenes of the audience reacting to the film at various points are lit with changes intended to give the impression that they are watching the film, however the aggressive changes in ambient room light are inconsistent with the scenes being implied on screen.

When at the airport, the same red and white car passes behind Mrs Travers and Ralph twice.

When the Goffs leave their house and travel on a train Ginty has a coat on but when they arrive at their new home Ginty is not wearing her coat.

Mrs. Travers finally grants Disney the film rights to her books, except she signs the wrong page of the contract - the Witness page, in the space reserved for the person in whose presence she should've signed the Signatory page. She cannot legally be her own witness; and what is more Mr. Disney's signature is also invalid since nobody witnessed that either, as shown by the unsigned space further down the document.

At the airport there is a sign stating "Trans World Airways -TWA". TWA stood for Trans World Airlines.

P.L. Travers never did warm up to the song "Let's Go Fly a Kite", as depicted in the film. According to Richard M. Sherman, it was "Feed the Birds" that actually won her over.

Tom Hanks portrays Walt Disney with dark hair and young-looking skin. By 1961 Walt had visibly aged, likely as a result of his heavy smoking, with graying hair and wrinkles.

Travers Goff is depicted clean shaven in all his scenes in the film, and Pamela insists that Mr. Banks must not have a moustache in Mary Poppins (1964), for this reason. However, Travers Goff's photographs show him with an even larger moustache than David Tomlinson's Mr. Banks had.

Mrs. Travers is shown to live alone at her London home, apart from her maid Polly - there is no sign of P.L. Travers' adopted 10-year-old son, nor her female life partner.

By the time this movie takes place her relationship with Madge Burnand was over and her son was all grown up.

When Walt Disney greets P.L. Travers at the main gate of Disneyland he greeted her with "Welcome to the Magic Kingdom". The Disney Park in Orlando is called "Magic Kingdom" not Disneyland in California. However, at the time the movie takes place, "Magic Kingdom" was (and still is to this day) a semi-official nickname for Disneyland.

Although Colin Farrell is from Ireland and Ruth Wilson is from the United Kingdom, they do in fact portray Australian accents in the Australian scenes. Annie Rose Buckley and Rachel Griffiths are both from Australia, and correctly maintain their Australian accents during the flashback scenes.

When Walt and Mrs Travers arrived in Disneyland for a visit in the morning with people were queuing for the gates to open the clock tower at the train ride shows it was filmed about 3:30pm. This appears twice on screen.

Where Helen Goff is riding the horse bareback with her father, a saddle girth strap is visible in a shot of their legs.

The machine supposedly playing an archive recording in the closing titles begins near the end of its tape, which dramatically runs out as the credits move on. However, since these recordings were in effect contractual documents, each negotiation session would have begun with threading a fresh tape; not one with such limited time.

The other drivers at the airport hold signs bearing logos of Warner Brothers and MGM adopted sometime after 1961.

When Travers arrives in her hotel room, there are two Winnie the Pooh dolls among the gifts, showing Pooh in his redesigned appearance from the late 1960s. Walt Disney's merchandise licensee did not yet have the toy rights to this character in 1961.

When Mrs Travers arrives in her hotel room she pushes a button on the remote and the TV comes on immediately. In 1961 when the movie is set, TVs used vacuum tubes and it took ten seconds or more for the TV to warm up. The first TV with an "instant on" feature wasn't marketed until 1968 by Westinghouse.

Several changes had been made to real-life Disneyland to make it look like how it was during Walt Disney's lifetime (i.e., the area in front of the train station is lined with posters advertising the park's attractions). However, Fantasyland remains unchanged despite going through a complete overhaul in 1983, some twenty years after the release of Mary Poppins (1964).

In 1961 the overhead shelves of prop and first generation jet airliners were for pillows, blankets, and coats only. Any carry-on luggage had to fit under the seat.

In the film's final scene, where the camera pans past the weather vane, shadows on the vane itself and elsewhere show that the sun is in the southern sky. Australia is in the southern hemisphere, so the sun is always in the northern sky there.

It was not possible to travel directly from Maryborough to Allora by train in 1906. It would have required changing trains twice, in Brisbane and Toowoomba.

In 1961, Travers is shown living at 29 Shawfield Street in Chelsea. At the time P.L. Travers still lived at her most famous residence, 50 Smith Street, four blocks to the northeast. She did not move to Shawfield Street until 1962, once its renovations were completed.

The railway destination board, at Maryborough Station contains a number of errors. There is no such town as Vandina, it is actually Yandina. Grandchester is incorrectly spelt as Grgandchester. The stations shown below Brisbane are not on the old Gold Coast branch, but are inland, with the destination, Allora, a real town, approx. 150km inland from the Gold Coast.

The railway poster shows Allora as the end of the line. In fact the end of the line was at Goomburra, some 12 miles east of Allora.

In the finest tradition of movie billboards and DVD covers everywhere, the new poster for Mary Poppins (1964) credits "Julie Andrews" above the face of Dick Van Dyke, and "Dick Van Dyke" above the face of Julie Andrews.

Mrs Travers insists on the colour red not being in the film, but in Mary Poppins (1964) the title character wore a red coat in the Chim Chim Cheree scene.

Walt Disney tells Pamela that he had a wager on whether he could get her on a ride at Disneyland. It seems odd for him to do so without apparently having any witnesses to him succeeding.
