Book excerpt: The subjects of this book constitute a significant cross section of BBC science fiction television. With such characters as the Doctor (an enigmatic time-traveling alien), Kerr Avon (a problematic rebel leader), Dave Lister (a slovenly last surviving human) and Captain Jack Harkness (a complex omnisexual immortal), these shows have both challenged and reinforced viewer expectations about the small-screen masculine hero. This book explores the construction of gendered heroic identity in the series from both production and fan perspectives. The paradoxical relationships between the producers, writers and fans of the four series are discussed. Fan fiction, criticism and videos are examined that both celebrate and criticize BBC science fiction heroes and villains.
