Buster Keaton's "Cops" is a very funny and very well-crafted short comedy with a wide range of comic material, ranging from subtle timing gags to hilarious slapstick, and featuring some impressive choreography as well. It takes a short while to set everything up, and then it is very humorous the rest of the way. Keaton's character is involved in a series of misunderstandings at the beginning of the film that eventually lead to him driving across town in a rickety carriage filled with things that don't belong to him. Soon he is being pursued by (literally) every policeman in the city. There are plenty of laughs from Keaton's own comic skills, and a lot of large-scale chase scenes that are carefully filmed and very entertaining.
This is a movie not to be missed for anyone who enjoys silent comedies.
