Considering the title and the involvement of director Jon Favreau, whose pre-“Iron Man” background was mostly in comedy, I had assumed it was going to be a science-fiction comedy along the lines of “Men in Black.” I was apparently wrong. Anyhow, watch as Daniel Craig, Harrison Ford, and a bunch of mysterious whatsits face off in the first trailer for the long-awaited, and apparently quite tense, “Cowboys and Aliens.”

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.
