Despite not having a deal with Mad Men creator-executive producer Matt Weiner yet, AMC is officially moving ahead with a fifth season of the Emmy-winning period drama, exercising its option with the series' producer Lionsgate TV. (The cable network made a similar move two years ago when, along with Lionsgate, it was again embroiled in difficult renegotiations with Weiner.) Because of the protracted talks with Weiner, referred to in a statement by AMC as "key non-cast negotiations," the premiere of Season 5 is being pushed from the summer to early next year. Here is the full statement: "AMC has officially authorized production of season 5 of Mad Men, triggering our option with Lionsgate. While we are getting a later start than in years past due to ongoing, key non-cast negotiations, Mad Men will be back for a fifth season in early 2012."
