Director Martin Scorsese stages some beautifully choreographed violence in "Boxcar Bertha", his first studio film, but he had yet to break through to his actors, and much of the picture is stilted or awkward. Barbara Hershey plays Bertha Thompson, a teenage orphan in Depression-scarred Arkansas who falls in league (and in love) with a union organizer; they're joined by a black harmonica player and a Yankee card-shark to take revenge on the railroad company by robbing the trains. Adapted from Ben L. Reitman's book "Sister of the Road", Scorsese as a filmmaker is a bit misplaced within this milieu--the 1930s doesn't seem to be his thing--and while the film has atmosphere, it lacks visual assurance and nuance. Similarly, Hershey doesn't seem to connect with the Depression, either; with her dreamy eyes, flowing chestnut hair and penchant for throwing her lines away blithely, she's more like a Boxcar Hippie. Still, Scorsese uses her well at certain moments, particularly early on when she's shooting craps around a campfire, correcting a friend about her surname, or staring out a rain-soaked window. She also looks great chasing after locomotives, and the train sequences are all well-filmed. The finale, a slaughter out in the middle of nowhere, packs a visual wallop. It seems certain the youthful director saved his creative juices for this sequence, and his cinematic prowess suddenly flairs up. Visceral and expressive, this showdown turns the story around from mere exploits of low-class gangsters into something far more profound: a sorrowful human tragedy soaked in consequence and fate. **1/2 from ****
