Think the Mitt Romney vs. Newt Gingrich feud is nasty now? It's about to get worse.

The Daily Beast reports that a pro-Gingrich super PAC has purchased a 30-minute attack video called "When Mitt Romney Came to Town." The intriguing part of the story is the man behind the video is an ex advisor to Romney.

When Mitt Romney Came to Town focuses on four case studies of Bain’s acquisitions—a Florida-based company called UniMac, which produced commercial laundry equipment; KayBee Toys; the electronics company DDI; and AmPad, an Indiana-based office-supply producer. The key result of these transactions, the film asserts, was “spectacular returns” for Bain through “stripping American businesses of assets, selling everything to the highest bidder, and often killing jobs for big financial rewards.”

While the film itself tells a pointedly polemical tale of corporate greed, the story behind the film has undertones of bad blood, and even vendetta.

The filmmaker, Jason Killian Meath, is an award-winning director who worked on Romney political ads in Romney’s run against John McCain in 2004. When Romney retained the services of SSG for his current presidential bid, Meath was not part of the team. Meath declined to comment on the film, or upon his motives in making it.

A Winning Our Future representative said that the PAC has not yet decided how to use the film, though it is expected to be widely distributed through the news media, now congregated in New Hampshire, as early as this weekend. Saturday morning, they launched a website, called kingofbain.com, featuring a two-minute trailer from the video.
