...The Other Side of Bonnie and Clyde (1968)

Warren Beatty's Bonnie and Clyde is vilified by some for its glorification of the criminal couple's exploits and The Other Side of Bonnie and Clyde sets the record straight, according to the estate of their nemesis lawman (and movie villian) Frank Hamer. Actual video footage from the criminal couple's massacre, photographs, interviews, lame dramatizations, and a polygraph machine that sits silently between the interviewer and the ex-criminal he is interviewing (you gotta see it to believe it) form the story arc that is at once familiar yet most probably more in line with the truth than the classic film. If Bonnie and Clyde (the couple) are your obsession, you won't want to miss this; it gets a lot less necessary after that.

...The Trial of Lee Harvey Oswald (1964)

The Trial of Lee Harvey Oswald is a straight-ahead filming of a mock trial of the presidential assassin, performed in a courtroom setting, that stops dead (pun intended) two-thirds of the way through for five minutes as an interview about Cuba with the real Lee Harvey Oswald is played for evidence. Historically it might be nice to have this on record but cinematically we're not talking Citizen Kane. The film has no music or audio other than what the actors speak, and the judge literally looks at the camera when talking to the jury; Court TV it ain't but it was filmed in Dallas in 1963 in the weeks following the actual assassination so that's worth...um...something?
