AMC also announced premiere dates for the highly anticipated returns of Mad Men and The Killing.

The Killing will also kick off its new season with a two-hour premiere, on Sunday, April 1 at 8/7c. (Coincidence that it returns on April Fool's Day? Discuss.) The murder-mystery drama moves to its regular timeslot, 9/8c, the following week.
