This is one of Harold Lloyd's most entertaining comedies, with Lloyd, Jobyna Ralston and John Aasen making good use of a variety of material, especially a lot of Absurdist-style gags and routines. It starts just a little slowly in setting things up, but once it gets going, there are a lot of good laughs without a slow stretch.
Lloyd plays a good-natured but completely oblivious upper-class hypochondriac who travels to the tropics for a rest, and finds himself in the middle of a chaotic revolution. His naive initial reactions to the situation are quite amusing, and few screen comics could have pulled them off as well as Lloyd does.
As things get hotter for Lloyd and Ralston, the hilarious giant Colosso (Aasen's character) joins the madness, and that leads to some even more humorous gags. The lengthy sequence resulting from the first meeting between Harold and Colosso is very cleverly done, squeezing more than you would ever have guessed possible out of a simple situation. Afterward, Colosso's size and strength are used in many imaginative ways, with a lot of rather elaborate sight gags that are set up nicely.
The whole thing works very well. Once everything is set up, it flies by so quickly that it seems only to have taken a fraction of its running time.
