Not so much another retelling of a year of "Doctor Who" as the ultimate reference guide to Season 12 of the series, "Doctor Who: The Scripts, Tom Baker 1974/5" tells virtually everything you could want to know about the production and execution of "Doctor Who" in the first year of Tom Baker's tenure as the Doctor. Included here are the scripts (complete with changes made during shooting) for all 20 episodes across the 5 stories of the year, story histories, production notes, casting choices, transmission information, music notes, prop histories and inventories, scene sketches and maps, reproductions of newspaper clippings, notes on potential but unmade stories, changes made for American TV, audience reaction polls, and a ton of footnoting for just about every reason imaginable.
More than any other behind-the-scenes science fiction book I've read, this one really tells you what tough choices and concessions had to be made, why they chose person A over person B, what got cut for budgetary reasons (a common problem with Doctor Who) and what concessions (or lack thereof) were made for continuity. This book is a massive undertaking, and, indeed, authorship is spread between numerous people. If there is a question you want answered about Season 12 of Doctor Who, the odds are really good it's in here somewhere.
While I find it hard to recommend this book to the casual Doctor Who fan, it's invaluable to the die-hard Whovian or the student of film or TV production. This is simply the finest production book I've read and I dearly hope to see them tackle other seasons in the same way in the future.
