That line’s on-the-nose, and the movie has its share of such moments. As with any biopic, plenty of liberties are taken: Laurel & Hardy’s various UK tours in the late 1940s and early ‘50s are compressed here into one, and there’s no mention (comedy nerd alert) of the team’s grim final film, “Atoll K.” Little matter. The grace and tact with which Reilly and Coogan create their versions of these men never pushes for effect. It’s a modest film, but a very good one, and by the end I was quite moved by its valiant belief in decency and in the duo’s eternal appeal.
