A documentary is a piece of non-fictional media, often screened in movie theaters. In the movie review series On Cinema there is a long-running debate if documentaries are true movies or not. Frequent guest Gregg Turkington considers them poorly made and uninteresting movies at best,^[1] and doesn't even consider them movies at worst. He usually rates them poorly, if at all.

Turkington has claimed that the documentary Trinity & Beyond may have used faked footage in its production.^[1]

Similar to documentaries, concert movies do not have actors, instead filming actual events.
