I just watched and truly enjoyed the movie American Pastime. Because I've read and taught about the internment (imprisonment in isolated camps) of Japanese Americans during World War II, I was interested in this film, and can now recommend it.
Books you could read about the internment include Journey to Topaz by Yoshiko Uchida, Farewell to Manzanar by Jeanne Wakatsuki Houston and James D. Houston, The Journal of Ben Uchida (a My Name is America novel by Barry Denenberg based on true events), Caged Eagles (about internment in Canada) and a picture book titled Baseball Saved Us by Ken Mochizuki and Dom Lee.
