The whole point of THE FROZEN NORTH has dated and would be lost on 99.99% of the general public, though this doesn't make it a less enjoyable film. Still, I would not introduce someone to Keaton with this short, as this short is meant to be Keaton acting out of character. The dream ending is Keaton's way of saying this is not the real Keaton, and the whole point that has dated, something an audience of 1922 would understand, is that Keaton is parodying film stars of the day, the main one being cowboy actor William S. Hart. The whole tear sequence angered William S. Hart to the point where he didn't speak to Keaton for two years. I will also mention that as a silent film buff myself, Hart is one of the few major silent film stars who I have not seen a film of yet, so I need to remedy this. Also, later in the film, when Keaton turns into that monocled aristocrat - that would be a parody of Erich Von Stroheim. Again, only hardened silent and old Hollywood buffs would get that today, but back in 1922, common knowledge. Von Stroheim would most famously be linked to Keaton twenty eight years later as they both played silent film relics in Billy Wilder's SUNSET BOULEVARD, a film I highly recommend.
Also, another treat for silent film fans in the scenery in this one. Filmed in snowy Truckee, CA., three years later, Charlie Chaplin would film THE GOLD RUSH in the same location, and yeah, the films have a similar look. Keaton even rests his cane in the snow, cane digging in the snow, causing Keaton to fall, just like Chaplin.
As far as gags, let's see...the ice fishing gag, as well as the guitars on feet as snowshoe gag, are from ROCKIN' THRU THE ROCKIES. The idea of singing maudlin acoustic guitar music in an igloo causing the comic to cry was later done in W.C. Fields THE FATAL GLASS OF BEER, directed by Clyde Bruckman. As far as Laurel and Hardy gag, you got me on that one, though when someone points it out to me, I'm sure I'll smack my head because I should've known the answer.
On a personal level, I'm going to give this a 10/10 with the admission that I'm a silent film nerd who would find things in this film the average person would not. The other great Keaton films, though, no background is needed, and yes, this film has grown on me over the years. It is fun for one time seeing Keaton play an adulterer, a murderer, a thief, and badly act on purpose taking a bullet in the back. Not standard Keaton fare, but I'm really happy this short exists. I wish it even existed more, because yes, what we have is incomplete. With an eighteen minute running time, I would imagine two - seven minutes are missing. If any film preserver finds a complete print and packages these shorts again, they'll get my money.
