While I haven't watched all of them, the extras that are included in the Adventures of Young Indiana Jones box sets appear to be first class. I'm sure you remember the series, Indiana Jones travels with his parents around the globe between 1908 and 1918. On his travels he runs into many dynamic historical characters that helped to shape the 20th Century. The documentary supplements that I have watched have been very well done and if I were teaching junior high or high school history I believe that I would be tempted to show these to classes. The dramatic situations make the characters so memorable.
