Another gem of musical film, "Fiddler" is my second favorite. Tevye's struggle to balance tradition with wanting to let their daughters follow their hearts is a good topic for family discussion, as are the issues raised by the deep faith, and treatment of, the Jews. (This is notable in part because one character respects his Jewish neighbors, yet is pressured into persecuting them). Again, the song and dance numbers will bring you great delight, and the overarching message of faith and family in the face of adversity will, too.
I recommend this for older children only, for several reasons. Length is an issue; know who is and isn't mature enough to sit through it. Moreover, younger kids may be confused at the social issues and traditions raised, and frightened by some scenes. (These include the violence at Tzeitel's wedding, a brief scene of revolutionaries being arrested, and the scary-for-youngsters Fruma Sarah scene). Also, parents will need to discuss Tevye's reaction to Chava's interfaith marriage. Even if your personal faith doesn't condone marriage outside its confines, please stress to young viewers that disowning a child for this or any reason--and moreover, in effect, saying that child is dead, is not acceptable. You may also need to discuss the slur "Christ-killers" with some kids. One scene features drinking and should be pointed out as negative as well. With this in mind, enjoy, and la chaim.
