The hapless overweight hero played by Jeff Garlin in this mild but likable Chicago comedy lives with his doting mother, works at Second City, won’t budge from his perfect parking place across from Wrigley Field, and hasn’t gotten laid in a long time. So his hopes are lifted when he meets a racy and kooky ice cream parlor waitress (Sarah Silverman). Meanwhile, he’s miffed that he can’t even get a tryout for the lead in a remake of Martya movie that he thinks describes his life, though he seems to forget that Ernest Borgnine played a butcher in that film, not an actor. The story ultimately lands in incoherence; but the cameos and local details, and even some of the gags, keep it perky. R, 80 min. (JR)
