Snowball is a character in George Orwell's Animal Farm. He is largely based on Leon Trotsky and describes how he led the opposition against Joseph Stalin (Napoleon), though he also includes elements of Vladimir Lenin. He is shown as a pink pig on the movie poster for the 1999 film Animal Farm, and is voiced by Kelsey Grammer.
Snowball believes in a continued revolution: he argues that in order to defend Animal Farm, he must strengthen the reality of Old Major's dream of a life without humans and that they must stir up rebellions in other farms throughout England. However, Napoleon always disagrees with any ideas that Snowball has because he does not want Snowball to lead Animal Farm and gain more popularity than himself.
Snowball also writes the first version of the Seven Commandments. They are later altered by Squealer under the orders of Napoleon, to accommodate the actions of the pigs. For example, the commandment stating "No animal shall drink alcohol" is changed to "No animal shall drink alcohol to excess", and is later replaced with the rest of the commandments as all animals are equal, but some animals are more equal than others. The rule that states "No animal shall sleep in a bed" is changed to "No animal shall sleep in a bed with sheets".
Snowball is eventually forced out of the farm when Napoleon uses his guard dogs to attack Snowball. After that, he is blamed for problems on the farm, and it is believed he was in support of Jones from the start as well as sowing seeds with weeds. Though he fought bravely at the Battle of the Cowshed, the facts are altered to say he openly fought for Jones and that the shot wounds are changed to wounds Napoleon inflicted on him. Those accused of supporting him are executed after being forced to confess, and a reward is offered for his capture.
Snowball is an inventive pig who influences others to his side with intelligence and compassion. It is never revealed what happens to him after his escape. In the 1954 animated adaptation it is implied that the dogs kill him. However, in the 1999 live action film adaption, he is shown escaping the dogs and surviving, though Napoleon declares him banished under pain of death.
When the novel Animal Farm was adapted for screen in the 1950s, the CIA investors were initially greatly concerned that Snowball was presented too sympathetically in early script treatments and that Batchelor's script implied Snowball was "intelligent, dynamic, courageous". A memo declared that Snowball must be presented as a "fanatic intellectual whose plans if carried through would have led to disaster no less complete than under Napoleon." De Rochemont subsequently implemented these changes.
