So you know him as person, or did you just read the crap and rumours from the newspapers and web sites? After career like that, it is just OK to be an asshole. I have watched few interviews done his later years, and he seem to be a man who has reasoned opinions, and who say what he thinks
He invented "Video Assist".He also made elaborate home movies that can never be shown in public without a lot of clearance issues.
So you came to that conclusion from watching his interviews? Pot calling kettle black. His own children in an interview long before his death stated how brutal he was at home. When he had a bad day at wok he came home yelling at everyone and taking it out in them. They said in a very large home it was very difficult to hide from him because he looked for them to bitch them out. Not only that for an example but the many many other reports over the years of volitile angry behavior to others. Where there is smoke................
He smoked like a chimney, watch all his vids (interviews, his telethons, etc...)And lived to his 90's George Burns also.
