Speaking of tension and Harrison Ford, I’m a little bit afraid to watch what might become Mr. Ford’s rather legendary “Conan” appearance last night, in which most viewers agreed Ford was in some way altered — perhaps by booze, perhaps something prescribed as medicinal.

All I can say is that, if true, it wouldn’t be the first time. L.A. science fiction geeks of a certain age remember a radio interview given by a young Ford and Mark Hamill before the release of the very first “Star Wars” in which the twosome, who apparently were convinced they were the stars of a movie that might, at best, become an obscure cult item, were fairly obviously under the giggly influence of some pretty good cannabis. The late host of Pacifica station KPFK’s  “Hour 25” radio show, Mike Hodel, often said it was a low-point of the program.
