I watched Saving Mr. Banks last night.  Saving Mr. Banks is a 2013 movie about Walt Disney’s attempt to get the rights of Mary Poppins from the book’s author, Pamela Travers, so he could make the movie Mary Poppins. 
 In the process, we learn about the demons with which both Travers and 
Disney are wrestling—-their difficult pasts and their attempts to move 
on.
The title Saving Mr. Banks refers to the father in the movie Mary Poppins,
 and also the book.  Mr. Banks in the movie is distant from his children
 and wants a nanny who will train his kids to be disciplined, like 
soldiers; he does not appreciate the new nanny, Mary Poppins, coming 
along and taking his kids on fun adventures.  At the end of the movie, 
however, Mr. Banks is flying a kite with his kids.
I do not know exactly how this played out in the book.  I was reading
 on wikipedia, and what I got is that Mr. Banks in the book is not that 
big of a character, and that he was actually rather kind to to his 
children.  The stern picture of Mr. Banks in the movie may have been 
based more on Walt Disney’s harsh father; Disney insisted that Mr. Banks
 have a mustache, against Mrs. Travers’ objections, and the reason was 
probably that his own father had a mustache.  Mrs. Travers’ father still
 had issues, however, for he was a drunk, and he dismissed a poem that 
his daughter wrote when she was a child.  He was still a fun, loving 
dad, though.  When Mrs. Travers was a child, her father was sick and 
dying in bed, and her mother unsuccessfully attempted suicide.  In swept
 her aunt, who was like the eccentric Mary Poppins of the books and was 
bringing order to the collapsing home.  Unfortunately, the aunt could 
not fix everything, and the father died, disappointing the little girl. 
 She would grow up to write Mary Poppins, about a nanny who really could save the day.
There are fact-checks all over the internet about this movie.  I 
would not be surprised, though, if there actually was some deep-felt 
need on the part of Mrs. Travers to save her father and to move on, even
 if Mr. Banks was not as prominent in her book as he was in Walt 
Disney’s movie.  The movie is based, at least in part, on audio 
recordings of actual meetings that Mrs. Travers had with Walt Disney’s 
employees, and we get to hear one of them at the end of the movie.
One aspect that I enjoyed about Saving Mr. Banks was the 
relationship between Mrs. Banks and her Disney-commissioned driver, 
Ralph (played by Paul Giamatti).  The curmudgeonly Mrs. Banks at first 
does not like Ralph’s chipper attitude, thinking that it reflects the 
typical Disney sap that is all around her.  But she gets to know Ralph 
better and learns that his daughter has polio and is consigned to a 
wheelchair, and Ralph tells her that he is so concerned about the 
weather because he wants for his daughter to enjoy the outdoors rather 
than being cooped up in her room.
Another part of the movie that I appreciated was when Walt Disney was
 talking with one of his songwriters, and Disney was telling the story 
of when he was a simple artist with a notepad, and a big shot was trying
 to buy Mickey Mouse.  Disney said no, for Mickey was family.  Although 
Disney struggled throughout the movie to understand Mrs. Travers, he 
could identify, on some level, with her feelings for her character.
The song “Let’s Go Fly a Kite” has been in my head since I watched Saving Mr. Banks.  It has more of a sentimental association in my mind now than it did when I watched Mary Poppins
 itself, and the reason is that, now, it relates to the healing that 
Mrs. Travers found, at least in the movie.  It represents the attempts of 
Disney’s employees to understand where she was coming from—-to include a
 scene of redemption for the father because that was what she wanted.  
And it brings to mind the moving scene of catharsis later on, as she 
watches Mary Poppins and cries as “Let’s Go Fly a Kite” is being sung.
Some have criticized Saving Mr. Banks because they feel that
 it depicts Mrs. Travers ultimately giving in to superficial Disney sap,
 as if that can solve all the world’s problems.  In actuality, Mrs. 
Travers was disappointed with the movie Mary Poppins.  People 
are entitled to their opinion.  Speaking for myself, I like sap.  I 
enjoy stories about healing, love, reconciliation, and being 
compassionate to people where they are.  That includes Saving Mr. Banks, even if it diverged from what really happened, in significant areas.
