Filming on Emmy-winning show "Mad Men" has been put on hold as financial wranglings between TV executives threaten to push the next season back until 2012.

The fifth season of the series, which stars Jon Hamm and January Jones, was due to start shooting in April or May for a summer premiere. But bosses at the network behind the show, AMC, have reportedly failed to agree on a deal with Lionsgate, the studio which makes the series, leading to lengthy production delays.

According to the New York Times, the Season 5 premiere will likely be pushed back to 2012.

Series creator Matthew Weiner spoke out about the financial dispute back in January, telling Entertainment Weekly, "They [AMC and Lionsgate] 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."

Hamm recently admitted he didn't know when he would be getting back to work: "We're still in limbo. Usually we start shooting in April or May, and it doesn't seem like it's happening now."
