Temple Grandin is an autistic person whose life was documented in an HBO biopic starring Claire Danes. Her whole life has been devoted to the ethical treatment of animals, especially cattle.
When I rented the movie from my local movie rental, I was awed by the production values and Grandin's story, awesomely portrayed by Danes. Then, I watched the film again with the director's and Temple Grandin's commentary and it gave me a new look into what the story was really about.
Highly recommended. HBO has been making great cinema for some time. This is a gem. And it is all about cattle, and autism, and ethics, and a person who rises way above expectations.
Temple Grandin has also given a TED talk, and it is classic autism advocacy by a person who knows what it is about.
Sorry, didn't mean to highjack the thread with autism advocacy, but Grandin, above all, seems to understand cows. So, I thought it might be helpful to this post.
