Continuity mistake: Travers rides in a stretch limousine and Ralph, her driver, always puts her in the seat farthest back at the rear window. However, whenever she is seen inside the vehicle, she is sitting right behind Ralph, and easily reaches over and slides shut the window between the front seat and the back, even though there should be a wide space between where she is sitting and the driver's seat.

Factual error: When Mrs. Travers arrives at the airport, there's a driver holding a name-card with a Warner Bros. Television logo on it. It's a far more modern version of the logo, however - in fact, the word 'Television' didn't appear in the ribbon across the shield until 1994. (00:10:10)
P.L. Travers: I will not have her called Cynthia, absolutely not. It feels unlucky. It should be something warm, a bit sexy. How about Mavis?
Trivia: In the final scene from Walt Disney's office when P.L. Travers has arrived for the premiere you can spot a map of Florida with a marked area of where today's Walt Disney World is located. Walt Disney was indeed planning WDW in 1961 and it was in the early stages of development on the drawing board. Ultimately, Walt died before the new park opened. (01:50:40)
Answer: The dog is either a Skye terrier or a French Briard. Since it is white and has a long tail it is most likely a mixed breed, since the scene is supposed to be in Australia, it may be a mixed terrier and Australian sheep dog mix.
