This movie version of Steinbeck's short novel, Of Mice and Men, is stellar. It stays very close to the original story, and fills out the characters in the book very nicely. Lon Chaney Jr. plays Lennie, who is simple-minded, trusting and sees the world in black and white terms. Burgess Meredith plays George, his companion and caretaker, who alternates between cruelty and tenderness in his treatment of Lennie. The two are constantly on the move, as Lennie "always does bad things" that get both into trouble. Tragedy is inevitable when Curly's wife tries to make friends with Lennie, and his actions toward her are misinterpreted as an attack. Lennie's strength and inability to read people are what make him "do bad things."
One of the dominant themes in the movie has to do with the value of life, both human and animal. Many of the main characters in the story are what could be termed "throwaways" - one is black and crippled, another has only one arm, Lennie is intellectually disabled, Curly's wife comes from a broken home and is damaged by emotional abuse, and Curly, the rancher's son, is short and physically unimposing. As we glimpse into the lives and personalities of the characters, we see that each one has good points - Lennie tries to see goodness in everyone, loves creatures that are gentle and throws his trust toward anyone who shows him some decency. One-armed Candy is compassionate toward anything with limitations; he sees the way he'll eventually be treated when one of the ranch managers convinces him it's best to shoot his crippled, blind old dog. Crooksie, the black cripple, understands what it is to be an outcast. Mae wants to feel as though she's worthy of being loved, and George enjoys being needed and feels respected and responsible, not just for Lennie, but eventually for Candy and Crooksie too as they all plan to buy a small farm together. The movie was made in 1939, three years after Hitler had become Germany's leader and at a time when details of his "Final Solution" were becoming public knowledge, making the judgments regarding the value of all of these people by the ranch owner and his son more significant.
This is not a "feel good" movie, but it's well worth watching. The story and themes contained in it are just as relevant today as they were in 1939.
