In David Osit's new documentary, "Predators," the director includes a short clip from a mid-two-thousands episode of "Jimmy Kimmel Live!" in which the late-night host-his free-speech tussle with the Trump Administration, at this point, not even close to a glimmer in his eye-is introducing the news journalist Chris Hansen to viewers. "Our next guest is the host of the funniest comedy on television. It's called 'To Catch a Predator,' " Kimmel says with a grin, as the studio audience's laughter rings in the background.
