The Doomsday Contract (unproduced TV story)

The Doomsday Contract also known as Shylock was an unproduced serial due to be part of Season 17. John Lloyd wrote the story using elements from his unproduced novel GiGax. It would feature the Doctor saving Earth from a corporation that wishes to buy it in order to receive a matter-transmutation device. Lloyd was asked to rewrite the script a few times and eventually he gave up to work on Not the Nine O'Clock News. Douglas Adams, with Lloyd's permission, allowed Allan Prior to rewrite it, but his script was rejected. Adams then gave the project to another author to be part of Season 18, but Adams soon left the series and the serial was ultimately cancelled.
