Congratulations, Universal! After audiences were apparently found to be amused to the point of joyous laughter while watching Cowboys & Aliens’ first trailer, the studio was worried nobody would understand that this, you know, wasn’t supposed to be funny. Well, a longer, more-revealing trailer is here, and — with its traumatic flashbacks, horrifying vacuumlike alien abduction, nudity of the seemingly non-voluntary variety, and, most of all, overtones of ethnic cleansing — it really doesn’t make you feel much like smiling. A quick suggestion, though: At one point, Daniel Craig leaps off a horse and onto the top of an alien spacecraft floating above a ravine in the desert, and that looks like good, clean, summer-movie fun. Perhaps consider excising that for the final cut?
