Two Artists on a Long Construction Journey There's a reason that breaking rocks is a time-honored form of hard labor. In "Triumph of the Wall," the first-time filmmaker Bill Stone all too faithfully records his morbid fascination with a stonemason's attempt to build a 1,000-foot wall on a Quebec estate. Neither the very relaxed pace of this builder, Chris Overing, nor Mr. Stone's sporadically amusing neuroses about his filmmaking make for a gripping documentary. Mr. Stone desperately tries to wring insights from his creative block and his insecurities about finding a structure for the film. It doesn't help that in his voice-over he tries to mimic the distinctive delivery of the filmmaker Ross McElwee, who directed the classic personal documentary "Sherman's March." By the time Mr. Stone declares his loss of focus a half-hour into the film, it's more likely to elicit sighs of impatience than chuckles. As a subject Mr. Overing might have yielded a passable standard portrait, but Mr. Stone gets bogged down in his feelings of being bogged down. Constantly underlining his own dissatisfaction, he trains the audience only to feel dissatisfied, and a final trip to Scotland, a historical center of dry stone wall-building, loses its impact. As weeks of chronicling drag into years, Mr. Stone achieves the effect of a horror movie, making you shout at the screen: "Run!"
