I can’t remember when or why I put Miss Potter in my Netflix queue, but I’m very glad I did. I watched it while sewing one evening last week and then again on Sunday afternoon with Twirly Girl, thinking she might also enjoy this film (she did).
I don’t know how many liberties were taken with the life of Beatrix Potter. The script largely follows her entrance into the world of being a published author and includes a healthy helping of chaste romance (you may want to keep a hanky handy). The main storyline as well as the occasional flashbacks show her at odds with her parents as well as the Victorian world about her. There are also a number of whimsical animated sequences involving Peter Rabbit and his friends that serve as our window into Beatrix’s mind.
As an aside (to amuse those who know I seldom can tell one actor from another), Lloyd Owen plays a role in this movie. I only recognize him because he was Paul in Monarch of the Glen. . .and I only mention it because he happens to be easy on the eyes (and ears, come to think of it). 
I was required to watch a documentary about Beatrix Potter when I was in college for children’s literature class. I was anxiously awaiting Miss Potter to be released and then I forgot about it. My mom and dad actually rented (and they rarely rent movies) Miss Potter and recommended it to me. I loved it too! I knew much of what was in Miss Potter from that documentary I had watched before. I don’t think Miss Potter completely stayed with the real story, but much of it was true. I dream of some day going to England and especially where Beatrix Potter lived, but I doubt that will ever happen.
My dad had an interesting comment. The movie ends with a statistic something like the Beatrix Potter tales are printed in more languages and read by more children than any other children’s book. My dad never read or had read to him a Beatrix Potter book until he read it to me as a child. My parents didn’t read all the classical stuff to me as a child, but Peter Rabbit was one of my favorites and I think we read all of the other Beatrix Potter tales at least once. My sister’s favorite was The Tale of Mrs. Tiggy-Winkle.
