La Charcuterie mécanique (The Mechanical Butcher) is an 1895 "humorous subject" (as classed by its makers) created by the Lumière Brothers.
[1] The action involves a live pig that is placed into a machine (essentially a large wooden container).
American Mutoscope and Biograph made The Sausage Machine the same year, which was a parody of the conveyor belt system.
The former showed simply a primitive crank, while the latter film depicted an electric machine with a reversible process.
[2] The film has been possible considered black comedy due to placing the machine into the pigs as pork and sell them that meant to be shocking.
