Trivia / Doctor Who S13 E6 "The Seeds of Doom"

---

• California Doubling: A quarry in Surrey doubles for Antarctica.
• Creator's Pest: Philip Hinchcliffe disliked the character of Amelia Ducat, feeling that the subplot featuring her was largely padding. When given the opportunity to novelise the scripts, he largely removed the character. Some fans objected vocally to this decision.
• Development Gag: A character is confused by the Fourth Doctor's appearance, saying he'd expected someone older. This is a reference to how Robert Holmes' original concept for the Fourth Doctor had been an elderly eccentric, but they'd ended up casting an actor who was younger than any of the previous Doctors had been (a controversial decision in the fandom at the time).
• Fatal Method Acting: A near miss — the roof of the TARDIS prop collapsed onto Elisabeth Sladen. Naturally, this would be the last time the original was used.
• Inspiration for the Work: Robert Banks Stewart was influenced in the writing of this ecological tale of rampant flora by his home abutting Kew Gardens as well as his familial connection to botanist Joseph Banks.
• Prop Recycling: As a cost-saving measure, the costume for the humanoid version of the Krynoid was adapted from an Axon outfit originally created for "The Claws of Axos".
• Recycled Script: Noticeably recycled from an episode of The Avengers (1960s) (not by the same writer). Also strong similarities to The Quatermass Experiment.
• What Could Have Been: There were talks of bringing the Brigadier and Benton back for the final episode, but due to the minuscule role, it was decided to be not worth the effort. Nicholas Courtney was offered the chance to reprise his role, but he was unavailable. When he watched the story and saw that it was a UNIT story without the regulars, his reaction was, "Oh, well."
