O’Toole has created an amazing body of work but “Murphy’s War” was the first film to come to my mind while reading this thread. I don’t think any other actor could have brought the intensity and determination to the role that he did. Absolutely nothing was going to stop him from sinking that submarine! Great film.
I think I read or heard in an interview of him that he had childhood fantasies of going over to kill Hitler.
It must have been in this interview—starts at approximately the 4:00 mark. This is an excellent interview of O’Toole BTW.
