Mr. Weiner has said he wants the show to continue, and AMC has pledged that it will definitely return, so the delay is largely due to a disagreement about money. As Mr. Weiner told Entertainment Weekly in January, apparently referring to AMC and Lionsgate, “They are fighting over a very lucrative property, and who is going to pay for it to get made; it’s one of the biggest perils of success — everyone wants a piece of it now, and they are fighting over who is gonna get the biggest chunk.”
