With a lineup of over 200 documentaries at this year’s Hot Docs Film Festival, it’s hard to fathom a time when the act of capturing reality was not possible. And yet, just over 50 years ago when D.A. Pennebaker began his work, there was no such thing as a documentary genre to speak of. Up until that point the act of capturing reality was reserved for mediums like news broadcasts or educational films, force-fed to teens in an effort to warn them against the dangers of sex, drugs, poor hygiene and other threats to American values. But even these non-fiction films, like any other Hollywood product of the day, required deliberate planning and set up, which didn’t exactly lend itself to the spontaneous nature of reality-proper.
