Trivia / Big Finish Doctor Who The Ultimate Adventure

• Doing It for the Art: Nicholas Briggs thought the play was terrible when he first saw it, and Terrance Dicks strongly disliked the way too sappy love songs that had been shoe-horned into his script. Both cooperated to record the story as a Big Finish audio play regardless just to preserve a classic piece of Who, including every little bit of camp and narm... and having so much fun in the process that they eventually made a sequel.
• Executive Meddling: The producers insisted on having balloon aliens (since they knew a way to make it look cool), a guillotine scene (since they knew a way to make it look cool) and three musical numbers. Terrance Dicks scrambled to come up with a plot that featured all those things, but eventually just gave up on trying to find a way to make the big romantic musical duet look believable. He later expressed relief at the fact that none of the producers happened to know a particularly well-trained group of circus seals that he'd have had to include.
• Recycled Script: Dicks lifted the sequence in which a companion pretends to be a Dalek and is seemingly exterminated before revealing they had already abandoned the Dalek casing from his earlier, less successful Seven Keys to Doomsday, which was also adapted by Big Finish.
