Joss Whedon produced another free comic book on the Internet, "Serenity: The Other Half". As a response to the 2007–08 Writers Guild of America strike, Whedon directed, co-wrote and produced "Dr. Horrible's Sing-Along Blog". It tells the story of Dr. Horrible, an aspiring supervillain, who shares a love interest in a girl named Penny with his nemesis, Captain Hammer.

Science fiction on television Cities of Gold" (1982), and "Ōban Star-Racers" (2006). The first Spanish SF series was "Diego Valor", a 22 episode TV adaption of a radio show hero of the same name based on Dan Dare, aired weekly between 1958 and 1959. Nothing was survived of this series, not a single still; it is not known if the show was even recorded or just a live broadcast. The 60s were dominated by Chicho Ibáñez Serrador and Narciso Ibáñez Menta, who adapted SF works from Golden Age authors and others to a series titled "Mañana puede ser verdad". Only 11 episodes were filmed.
