I have read many a Doctor Who Book, both offical and unoffical . I have absored more info that is proably healthy. Charles Norton has proably taken in even more Information in regards Doctor who films (both those that made it to the screen and those that havent) .
All that Information is here. Plots, behind the scenes Fiascos, little details of incident that might otherwise get missed. Everything. Including the Kitchen Sink. This is the definitive Book on the Doctor who at the movie (until the next movie make its to screen and an update is on the way) I only hope Charles Norton is able to do the 2nd edition in 2025 .
With so much research and its collections of facts and figures, with some wonderful writing, and a great eye for detail (see chapters discussing teletext, Films and film makers no one knows where they are or what happened to them or thier movies/scripts)
This book is highly recommended
