This is Stan Laurel and Oliver Hardy's first post Hal Roach film, at which point they are reputed to go into decline. And while most of the jokes feel like repeats (and it is in part a remake of their '31 two reeler Beau Hunks) this is an interesting film because it is so mythic. It's about two friends who are fated to squabble and endure eternally for the sake of companionship.
The tale even touches on death and the possibility they will be together beyond their lives. There's a scene where they are literally tied to each other, planning to both die simultaneously, dismissing the possibility that one of them might go on alone. There are routines that could be cut from Waiting for Godot, not yet written.
Stan doesn't look well and has put on weight. As has Ollie... They are older men. Ollie joins the French foreign legion (with his pal of course) to forget about a girl (Jean Parker). When he gets over his heartbreak, the duo decide they may as well go back to civilian life, only to discover it ain't that easy and they will face the firing squad at dawn.
Before the fadeout, Ollie dies, and actually comes back from the other side to be with Stan, though unfortunately as a horse! This is full of moments that can be dismissed just as gags but maybe, are an attempt to capture what is legendary about their alliance. And of course, through their films, they (sort of) really did achieve immortality.
