Mutant Enemy ProductionsMutant Enemy Productions is a production company that was created in 1996 by Joss Whedon to produce ''Buffy the Vampire Slayer.'' The company also produced the ''Buffy'' spin-off, ''Angel'', and his two short-lived science fiction series, the space Western ''Firefly'' and his high-concept ''Dollhouse'', produced by 20th Century Fox Television. Mutant Enemy also produced the internet series ''Dr. Horrible's Sing-Along Blog'' and the film ''The Cabin in the Woods''. Mutant Enemy produced the superhero series ''Agents of S.H.I.E.L.D.'' along with ABC Studios and Marvel Television. Most recently, Mutant Enemy produced the supernatural fiction series ''The Nevers'' for HBO.
Its offices (made out of glass bricks) were on the lot of 20th Century Fox in Los Angeles, previously the home of Chris Carter's Ten Thirteen Productions. According to March 2006's issue of UK magazine ''The Word'', the offices were closed not long after ''Angel'' was cancelled. Provided by Wikipedia
