|Doctor Who serial|
The Anti-Man manifests himself.
|Script editor||Robert Holmes|
|Length||4 episodes, 25 minutes each|
|Originally broadcast||September 27–October 18, 1975|
The expedition to Zeta Minor began with eight men. Seven were murdered. One survived - but he was not the murderer. The Doctor lands on the planet at the same time as the expedition's rescue team, and is immediately taken prisoner - the suspected murderer. But even stranger things soon begin to happen...
The plot was deliberately conceived by Philip Hinchcliffe, Robert Holmes and Louis Marks as a mixture of the film Forbidden Planet and the novella The Strange Case of Dr Jekyll and Mr Hyde. In addition, Marks had been reading science magazine articles about antimatter, and decided to write a story incorporating the subject. Hinchcliffe, in the first season in which he could commission new material, planned to move away from the "rubber-suited alien" theme, which he felt was clichéd. For this story he proposed having three separate monstrous elements: Sorenson's transformation, the anti-matter monster and finally the planet itself, claimed by Sorenson in episode 1 to be conscious of his group's motives.
The TARDIS picks up a distress call and the Doctor and Sarah arrive on the planet Zeta Minor. There they discover that a Morestran geological expedition has fallen prey to an unseen killer and only the leader, Professor Sorenson, remains alive.
A military mission from Morestra has also arrived to investigate. At first they suspect the Doctor and Sarah of responsibility for the deaths of the expedition members, but the culprit is eventually revealed to be a creature from a universe of antimatter, retaliating for the removal by Sorenson of some antimatter samples from around the pit that acts as an interface between the two universes.
The Morestrans take off in their ship, but it is slowly dragged back towards the planet due to the antimatter on board. Sorenson himself becomes infected by antimatter and gradually transforms into antiman, a monster capable of draining the life from others.
The Morestran commander, the increasingly unhinged Salamar, attacks Sorenson with a radiation source but this only causes him to produce multiple anti-matter versions of himself, which soon overrun the ship. The Doctor finds the original Sorenson, takes him back to the planet in the TARDIS and throws both him and his samples into the pit, fulfilling a bargain he earlier made with the anti-matter creature. Sorenson reappears unharmed, and the Doctor returns him to the Morestran ship, which is now freed of the planet's influence.

Despite the jungle setting of this serial, the shoot was entirely studio bound, and designer Roger Murray-Leach built an intricately detailed jungle set. The BBC was so impressed with it that they kept photographs of it for several years as an example of excellent set design and producer Philip Hinchcliffe recommended that he be nominated for an award for this work.
The original script had Sorenson dying after falling into the pit, but Hinchcliffe ordered that this be changed, as he felt it would too grim an ending for "the little ones", and because he saw Sorenson as a victim of the planet's influence rather than an evil man in himself.  Instead, a scene was added in which Sorenson is released from the pit, cured of his anti-matter contamination.
The most visible reference to Forbidden Planet is the anti-matter monster (Mike Lee Lane), which is sometimes invisible and otherwise is seen as red outlines. It bears a close resemblance to the film's "Creature from the Id". The monster is invisible in the filmed sections of the serial (where a wind machine was used to show its progress), and as outlines in the video sections (created with CSO).
The story was inspired by the movie Forbidden Planet and Robert Louis Stevenson's novella Strange Case of Dr Jekyll and Mr Hyde. In the DVD commentary Elisabeth Sladen, in a discussion about Forbidden Planet's influence from Shakespeare's The Tempest, compares Sorenson/Antiman to Caliban.
