The difference between "trained OK" and "trained perfectly" doesn't really matter all that much to me. I once did a film with Lassie. When that dog got excited he jumped all over Rudd Weatherwax [Lassie's trainer]. Now that's the smartest dog in the world. If the world's best-trained dog can jump around to show he's happy then my dogs should be allowed to do the same.

Bull markets are great, but they breed complacency. Bear markets can be energizing. Instead of fretting over the decline in your net worth, think opportunistically about all those bargains - and the potential gains when, inevitably, a bull market returns.

Frank called me one day and said, 'I have an idea for a movie, why don't you come over and I'll tell you?' So I went over and we sat down and he said, 'This picture starts in heaven'. That shook me.

Animals give me more pleasure through the viewfinder of a camera than they ever did in the crosshairs of a gunsight.

Fear is an insidious and deadly thing. It can warp judgment, freeze reflexes, breed mistakes. Worse, it's contagious.
