This is a very well-crafted short, but I've always been mystified as to why anyone, much less Stan Laurel, would consider this to be the first true Laurel & Hardy film. The first film they appeared in was a comedy starring Laurel with Hardy in support, "The Lucky Dog" from 1921. The second film they made together at the Hal Roach studio, "Duck Soup" (not to be confused with the Marx Brothers film of the same name, nor the Edgar Kennedy short), actually has humor more typical of their mature work.
If you can get past the unusual characterizations in "Philip" (Stan is a kilted, woman-crazy Scot and Hardy is his American uncle, fearful of being embarrassed lest someone find out he's related to this eccentric young man), the film offers some solid laughs. It's beautifully paced and edited; do try to see this in a theater with an audience, where it really comes to life.
The credited director is Clyde Bruckman, known best as a gag writer for Buster Keaton (and later Harold Lloyd, and still later, The Three Stooges). He only made 20 films as a director, but they include Keaton's "The General," Laurel & Hardy's "The Battle of the Century," Harold Lloyd's "Movie Crazy" and W.C. Fields' "The Man on the Flying Trapeze," each of these titles being among the best films their respective stars ever made. Producer Hal Roach was particularly fond of "Putting Pants on Philip," incidentally.
