The series will then move back to its regular 10pm slot for the second episode, which is directed by star Jon Hamm.
Weiner told TV Guide that he "didn't know the show would go on this long. [With the] part of the 60s [the show now depicts] I've always been fighting an image of the period that has been created by books and movies."
The fifth season left off in 1967, and reportedly the new season will jump ahead in time to the very late 1960s. All cast members will be returning, with the exception of Jared Harris.
