I am psyched that a live action version of the Last Unicorn is in the Works! I have loved the Last Unicorn ever since I was a little girl and I read the book for the first time a right after I graduated high school, and I was pleased how closely (for the most part) the animated movie by Rankin bass stayed true to the book. Like Penny Dreadful this story also holds a special meaning in my heart, it is my childhood and always stirs up my deepest memories.
My biggest concern is Amalthea. I am almost wondering if she should be completely computer animated when she turns human because I do not think a real human woman could capture the ethereal beauty of a unicorn incarnated in human form that Amalthea is supposed to be. The animated movie I felt really nailed it, and is the definitive "Human Amalthea" in my mind. Just look:
and even these still shots do not do justice to how she was animated in the film.
No joking, Lady Amalthea with Phoebe Cates in Fast Times at Ridgemont High help turned me into a man at age 4.
And would you put Amalthea in the same league as Red Sonja from the comics/books, Arwen from LOTR trilogy, Taarna from Heavy Metal, Teegra from Fire and Ice (1983), Deedlit from Record of Lodoss Wars, Princess Leia from Star Wars etc. when it comes to good looking fantasy gals or is she different than those characters?
Yet now that i'm a brony, i can't help but wonder how Amalthea in her unicorn self would look as an anthro like on FA/DA, i'm sure she'd be a foxy anthro unicorn just like Rarity in anthro fan art or Celestia.
