I was very surprised when I read a few of the reviews for this film, as apparently some time after NIAGARA FALLS was made, someone stupidly combined this film with MISS POLLY. While both are short Hal Roach films and star many of the same actors, combining them is like combining PLAN 9 FROM OUTER SPACE with STAR WARS! Sure, they're both sci-fi films, but other than that there is a huge gap in quality of the two pictures. Bluntly put, NIAGARA FALLS is a cute comedy whereas MISS POLLY is a pile of crap--merging them together must have resulted in a very confusing film indeed! I saw NIAGARA FALLS on Turner Classic Movies and it was shown in its original form--thank goodness. Now I am sure that many will think my score of 9 is way out of line, but I am NOT comparing this film to every other movie--just other short films (such as Roach's "Streamliners") and B-movies. I've actually seen quite a few of these post-Laurel and Hardy films by Roach Studios and this is bar far the funniest and best made of the bunch (and they do vary wildly in quality).
What makes this film so good is the quality of the writing. While MISS POLLY totally missed the mark, here with NIAGARA FALLS everything fell perfectly into place. One way I know it was such a good film is that my teenage daughter who is NOT a lover of old films like me still loved the film. Another way I know how good it was is that we both laughed repeatedly at the film. Sure, sometimes the humor wasn't 100% sophisticated, but it was funny--very, very funny. I particularly loved how outlandish the film became--such as the scenes with the gun and the very end of the film.
As far as the acting goes, it was fine but I don't know why Slim and Zasu got secondary billing--they (particularly Slim Summerville) were great. Zasu was not annoying (something she frequently was in other films) and Slim was like a walking cartoon character.
So if you'd like a good laugh and don't mind that the film is occasionally very silly, watch this movie.
