Joe E. Brown had a fondness for playing milquetoast characters forced into situations calling for acute athletic prowess, mainly because he was an excellent athlete himself. In Sit Tight, our hero, a would-be wrestler named JoJo, is forced to enter the ring and face down a musclebound masked opponent (Frank S. Hagney). Making matters worse, the masked marauder is convinced that his wife has been fooling around with JoJo. To pad out the storyline, JoJo is knocked out early in the proceedings, whereupon he dreams he's a sultan surrounded by harem girls. Contractually, Winnie Lightner was afforded top billing, and there's a sappy attempt at a romantic subplot involving Paul Gregory and Claudia Dell, but Sit Tight is Joe E. Brown's picture all the way.
