We’re causing a lot of break-ups across America!” says writer, comedian and actor Mike Birbiglia on his most recent film, “Sleepwalk with Me.” The film, based on his one-man-show and a spot on “This American Life,” details how Mr. Birbiglia figures out that he’s not ready for marriage to his longsuffering girlfriend, while at the same time beginning his career in stand-up … once he dropped his corny jokes and started to tell the audience about his relationship. The film makes uneasy viewing, as Mr. Birbiglia never flinches — in fact, he indulges — in showing his most weasely, reprehensible behavior. For commitment-phobes, it’s not a date movie, though it’s a funny one.
“Ira Glass and I have heard people have broken up after seeing it,” Mr. Birbiglia says. “And we don’t know how to take that. We don’t want to be the break-uppers, but if the movie affects people then that’s good.”
