Olympus: A Retrospective tells the behind-the-scenes story of the (fictitious) 70s British Sci-fi TV show, “The Olympus Chronicles.” Done in the style of such mockumentaries as “Garth Marenghi’s Darkplace” and “American Vandal”, Olympus lands a discerning eye on the early days of sci-fi television, and lovingly parodies the foundational shows of “Doctor Who,” “Star Trek: The Original Series,” and others. Starring Will Jacobs (The Other Two), Corin Wells (Black Lady Sketch Show, The Amber Ruffin Show), and Matthew Edward Matney (Upright Citizens Brigade), and produced and shot by Matt Antonucci (Mornin’ Sunshine, Adults Are Talking).
