Not bad at all as an actor. He played himself in “The Audie Murphy Story” too. Talk about multiple skills.
“To Hell and Back” = The Audie Murphy Story, which it often gets called (by me).
I always recommend the book ‘Picture’ by Lillian Ross about the filming of Red Badge. It’s a sympathetic portrait of a very young Murphy (and Bill Mauldin) who even in the book is portrayed as suffering from some obvious form of PTSD.
