Superman is already at the center of a legal battle between Warner Bros. and the estates of Jerry Siegel and Joe Schuster, but a new party is getting in on the tug of war from an entirely different front.

"Smallville" creators and executive producers Miles Millar and Alfred Gough, who left the series after the seventh season, are suing Warner Bros. TV for breach of contract, alleging that "WBTV made license fee deals with the WB and then the CW that 'were not arms-length.'""Warner Bros.' practices of unfair self-dealing include licensing the series for broadcast on its own affiliated WB and CW networks for unreasonably low, below-market license fees, resulting in lower gross revenues for the series and less compensation for plaintiffs, and failing to renegotiate the series' license fee to cover its production cost," the suit claims, according to The Hollywood Reporter.

THR reports that while damages were not specified, they could total in the tens of millions of dollars due to the longevity of the series. The show was just picked up for a tenth season. It's certainly hard to say how this will play out, but given the recent barrage of lawsuits, it's looking like lawsuits are the new Kryptonite for the (youngish) Man of Steel.
