Many great movies were already mentioned.
Spanglish is very easy to watch and deals with a Mexican mom dealing with her daughter growing up in America and becoming Americanized. It’s not nearly as serious as other movies and documentaries mentioned already, but I think it is a very enjoyable movie. It has a lot of humor and some serious moments.
Another is the Tuskegee Airmen with Cuba Gooding Jr. The true story about black men in the air force during WWII being trained at a southern base and later accomplishing successful missions during the war. Based on actual events.
The Long Walk Home with Sissy Spacek and Whoopi Goldberg about the bus boycott in Alabama? Or, was it Mississippi? That’s awful that I can’t remember which state. Sissy is one of the white women who helps to drive black people to and from work. Her husband isn’t happy about it and there is conflict in the community. Also, based on actual events.
