20 of the Best, Must-See Documentaries Ever Made — How Many Have You Seen?

Most documentaries I've seen have "VH-1 Behind The Music" in the title. I also enjoy anything about outer space. But as far as cinematic, artistic documentaries, the best I've ever seen is "When We Were Kings" about Muhammad Ali and George Foreman. Ali was at his transcendental apex -- a global figure -- he was probably the most famous person in the world at the time.

An international survey asked movie buffs about their must-see documentaries. Here's what they said:

• Restrepo -- soldiers in Afghanistan
• Planet Earth -- some of the best nature cinematography ever captured
• Children Underground -- impoverished children in Romania forced to live in the subways
• Dear Zachary -- a murdered man's parents do the unthinkable to meet their grandson
• The Bridge -- story of the Golden Gate Bridge
• King of Kong: A Fistful of Quarters -- seeking self respect, a man tries to break the Donkey Kong world record
• Senna -- Brazil's Formula One racing champion
• Jesus Camp -- Missouri kids get indoctrinated into a unique flavor of Christianity
• The Boy Whose Skin Fell Off -- the strong character of a man who battles a horrible disease
• How to Die in Oregon -- self-assisted suicide
• Jonestown: The Life and Death of Peoples Temple -- one of the most comprehensive projects on the Jonestown "Kool-Aid" story
• The Act of Killing -- Indonesian death-squads (reenactments in cinematic genres chosen by the perpetrators)
• Inside Job -- the cause of the Great Recession
• The Cove -- Japanese killing dolphins
• Blackfish -- Seaworld's orcas
• Shoah -- the Holocaust from both sides
• The Devil and Daniel Johnston -- "a portrait of madness, creativity and love"
• March of the Penguins -- probably the most famous nature documentary in 20 years
• Bowling for Columbine -- are Americans gun crazy or just plain crazy?
