Aside from is personal induced problems, he was a great actor.
I watched them film parts of the movie “The Stuntman” back in 1980 in Sacramento along the American River.
O’Toole was totally cold to any spectators in the area, basically ignored everyone, but the other actors and crew.
I was standing next to these 2 ladies (sounded like they were English) that were just devout fans, when he walked right past us. They were trying to get his autograph, and he acted like they didn’t even exist! He wouldn’t even say hi, look at them, or anything!
He wasn’t walking or talking with anyone... All by himself, right in front of our faces! I was thinking... “Man, what a bunghole!”
If that’s not the way he is, he sure left a crappy impression.
Now Alex Rocco, who was also in the movie was a TOTALLY COOL dude! He talked with anyone that wanted to talk with him, took pictures with anyone, even putting his arms around the people in the shots!
