It is recently released on video (check Blockbuster). It’s basically a documentary about a Father and a Son who go around the world and interview other Fathers and Sons. While doing so, they discover themselves as well as each other.
I highly recommend this movie to Men/Boys who have difficulty with their Fathers (difficulty not in sense of being disrespectful, but in a sense of “unable to understand his actions”). I am sure that Moms/Girls/Daughters will also enjoy this movie, but men will probably relate to this more than women.
