It's difficult to find anything new to write about this film - fellow reviewers on this site seem to have summed it all up. Yes, it is immediately reminiscent of Mack Sennett's Keystone Cop movies (note the 'C,' Mr MacIntyre), even though their films were still a good few years away. These garcons dans bleue look like they're having a rare old time as they caper about the sleepy Parisian streets (which look remarkably picturesque); they perform cartwheels and slide down banisters on their bellies in madcap pursuit of a cheeky little dog on the run with a choice leg of mutton clamped between it's jaws.
In the middle of this slapstick lunacy the focus is changed to a spot of camera trickery as we see the dog and the police seemingly scaling the side of a building. Of course the building is a painted canvas on the floor, and the shot is filmed from above. It's not long before you figure out what's going on, but even when you do it still looks pretty clever, and the actors playing the cops even try to place their fingers over the painted ledges, balcony walls, etc. to make it look as if they really are climbing the wall.
Of course it all looks pretty crude today - although it stands up well when compared to Sennett's cops - but, while it probably won't make you laugh, the sheer exuberance of this early slapstick will make you smile.
