60 free Blake's 7 trivia questions with answers — entertainment quiz, new questions added Aug 2026.
This Blake's 7 trivia quiz covers all four series of Terry Nation's BBC space opera, broadcast from January 1978 to December 1981. It starts with Roj Blake's show trial in The Way Back, follows the crew of the Liberator through the loss of Gan and the battle at Star One, and finishes on Gauda Prime with the bleakest ending British television has ever dared. The questions cover the characters and the actors who played them — Gareth Thomas, Paul Darrow, Michael Keating, Jacqueline Pearce, Sally Knyvette, Jan Chappell — plus the ships and computers (Liberator, Zen, Orac, Scorpio, Slave), the Federation and its drugs and domes, the pitch to the BBC as 'The Dirty Dozen in space', Dudley Simpson's theme, the low-budget locations, and the many revivals that never quite happened. Some are easy for anyone who watched at the time; a few will test even people who own the DVD box sets. Every answer has been checked against Wikipedia and each question carries a citation to the page it came from.
