The late Sam Shepard passed this story along four or five years ago. Definitely worth a listen. It’s a tale about a horse-riding stunt in The Right Stuff that didn’t go as planned, largely due to Shepard’s own steed being involved and a large black cable that may have resembled a snake. I’ve always hated The Right Stuff (I re-explained why eight months ago), but I’ll bet that the making of it was a great adventure.
