I’ll be reviewing the western “Appaloosa,” Ed Harris’ first directing job since “Pollack” when it opens in New York on Sept. 19. It saw it back in the city before it premiered here Friday night and it’s a well-acted old-school shot in the arm for the genre co-starring Viggo Mortensen, Renee Zellweger, and making his western debut, Jeremy Irons. Makers of contemporary westerns often fall into two traps. Either they’re incredibly long and pretentious — like “The Assassination of Jesse James,” which bowed here a year ago — or they pour on the gunplay so heavily they risk becoming ludicrous, like the remake of “3:10 to Yuma.” My interview with Harris appears today in The Post. He actually remembered that I spoke with him more than 20 years ago for the Bergen Record — the hometown newspaper for this native of Tenafly, New Jersey.
