Upon first look, “Comedy Bang! Bang!” is like any late-night talk show… until the guests sit down and the interviews commence. Then it veers off in all sorts of directions, most of which include unfiltered and improvised dialogue. The show is based on host Scott Aukerman’s popular podcast of the same name (and most certainly influenced by the Internet mock-talk show “Between Two Ferns With Zach Galifianakis,” which Aukerman produced and directed). In each episode, Aukerman reinvents the traditional celebrity interview by engaging his guests in ad-libbed banter, all of which is punctuated by beats from “bandleader” Reggie Watts.
