Arnold Schwarzenegger shares some stories from the filming of Conan
I got attacked by a dog on the very first day of shooting - he pulled me down from the rocks into a thorn bush and I had to be stitched up on the set. Milius walked up to me and said "this sets the tone" - he meant this in a positive way.
Also, it is true that I had to bite a real dead vulture because in those days they couldn't make one that would look good in a close-up. So they soaked it in alcohol to kill bacteria and dried it out. It still had lice.
