“American Dresser” (**1/2 out of four) was a pleasant but pedestrian road movie about a recent widower (Tom Berenger) who sets off on a cross-country motorcycle road trip with his lifelong buddy (Keith David) to re-evaluate their lives and their pasts. Unexceptional script is made palatable and easy-to-take by good performances, and a first-rate supporting cast including Gina Gershon, Bruce Dern, Jeff Fahey, and Penelope Ann Miller. Film buffs will note that Berenger and David play Vietnam vets and both starred as soldiers in Oliver Stone’s 1986 masterwork “Platoon.”
