That movie is on right now. Burgess Meredith is playing Ernie Pyle. The movie is "The Story of G. I. Joe." The captain in the movie is named Walker. But the the part of the movie concerning the delivery of his body and others to the roadside on a mule fits is Pyle's story exactly.
Thank you for the heads up. We attended the Memorial Day service at the VFW that is named after him in Belton, Texas this morning. The had the movie on when we arrived. We bought the DVD a few years ago.
My Mom tells me that they were not allowed to use his name beacuse the war was not over when they filmed the movie. She attended the premier with Robert Mitchum and still loves to tell the story.
