Novelisation

A novelisation was a book based upon a script in another medium, such as film. When the Tenth Doctor was trying to explain the mechanics of the infinite temporal flux to Martha, he suggested that it was like Back to the Future. Incredulous, she could only respond, "The film?" He then sarcastically replied, "No, the novelisation. Yes, the film." (TV: The Shakespeare Code)

According to Iris Wildthyme, there were Original Novelisations based upon a TV show about her. (PROSE: From Wildthyme with Love) She also claimed that Paul Magrs owned all 150 Terrance Dicks novelisations. (PROSE: Bafflement and Devotion)

In one meta-dimension, The seventeen-episode The Iris Wildthyme Show inspired a series of over 300 tie-in novels. (PROSE: Wildthyme Beyond!)
