The 1979 animated production looked like a 1970’s version of Narnia with the style of animation. I didn’t care much for the way the Pevensies were drawn.  The creators took too many liberties in their modernization of Narnia.  The movie made for television didn’t look like an old fashioned fairy tale even in the part of the story that took place in Narnia. I think it is important that both The Lion, the Witch, and the Wardrobe and The Magician’s Nephew at least have a vintage look with the parts that take place in Narnia which have a medieval quality. Didn’t C. S. Lewis admire old things like classic literature? The BBC version and Walden films succeeded at least partially in having something that looked like a medieval fairy tale.  I hope that Greta Gerwig will do something similar with the Narnia portion of the story even if she uses the 1950’s timeline.  Then at least part of the movie will appear as it is described in the book.  But I am beginning to have my doubts about any portion of her film actually looking like authentic Narnia. Hopefully the places in Narnia in her film will have some resemblance to the book.
