I caught Saving Mr Banks, on the making of the Mary Poppins Disney movie, on cable the other night. Worth seeing, especially if you prepaid via a cable subscription. Many reviewers praise the flashbacks to Mrs. Travers’ past and how it tied to her current behavior. Personally, I wasn’t that interested in why she was a pain. I just enjoyed watching the Disney team work their way through it.
The final scene has a tape recorder playing some of the original recordings between Mrs. Travers and the Disney team. I can’t be positive, but I believe my family owned a Wollensak T-1500 reel to reel tape recorder in the early 70’s.
