We review Invaders from Mars, the Big Finish Main Line release from 2002 featuring Paul McGann as Doctor Who. Ben and David laugh along with this fun story written and directed by Mark Gatiss and set at Halloween 1938. Gatiss creates a joyful pastiche from 1930s radio drama, gangster films, and a hearty dose of 1950s popular sci-fi done with the sketch-comedy stylings of The League of Gentlemen. Ben enjoyed listening to this with fresh ears nearly 18 years after its release and David wondered if the time fallout from Charley would have confused listeners as much as it did for him. Opening and closing music is by Alistair Lock's sound design for the story.
