I had a lot of fun watching this documentary about the rise and fall of American Gladiators. There are in-depth interviews with the Gladiators themselves about the production of the show and the behind the scenes drama. I would highly recommend it! 

ESPN did a good 30 for 30 film about American Gladiators too.

That doc was very good. I enjoyed it as well. I did see the 30 For 30 version on the screen at the gym today.
