Showtime Entertainment co-president Gary Levine said at the TV press tour of Shameless' 11th and final season airing in the summer instead of the fall: “We wanted it on earlier, because we wanted to strengthen our summer and we also wanted to provide a great lead-in for On Becoming a God in its second season. It just feels like a strong compatible lead-in.” Levine added that he doesn't know if Emmy Rossum will return for the final season. Rossum tweeted: "Bravo to an incredible run for a wonderful cast and crew, adding: "Eleven seasons is ten more than most shows get!" As for Weeds, which Showtime rival Starz is rebooting as sequel series, Levine said he passed because creator Jenji Kohan isn't involved. “The two integral elements of Weeds were Mary Louise Parker, but most importantly, Jenji Kohan. Our understanding is the sequel will not involve Jenji. That does not make it interesting to us," he said. ALSO: Read Shameless cast reactions to the show ending.
