It was a Walt Disney production in the mid-1960s starring Julie Andrews and Dick Van Dyke.

The movie was based on the book written in the 1930s by Australian-born, British-based author P. L. Travers.

Saving Mr Banks is the almost-true story of how Mary Poppins came to be the much-loved film.

The film has an incredible line-up of talent, including Tom Hanks as Walt Disney and Emma Thompson as P. L. Travers as well as Colin Farrell and Australian Rachel Griffiths as Aunt Ellie, the real-life Mary Poppins.

The story goes that Walt Disney's children begged him to turn their favourite bedtime story into a movie.

Little did he know that it would take so long to make good on his promise, and the biggest hurdle was simply trying to convince the book's author, P. L. Travers, to sign away the film rights.

Thompson plays an all-too-frosty cranky Pom, but she's saved by some truly warm and fuzzy moments.
