Twentieth Century Fox Film Corp. was hit with a lawsuit Wednesday, filed by a former studio executive who says he is owed unpaid bonuses linked to the show’s recent syndication run, according to The Hollywood Reporter’s Hollywood, Esq. blog.

Edward Gradinger, the former president of New World Pictures, sued the successor company Twentieth Century Fox Film Corp, which bought New World. Gradinger was president of New World’s TV group when it debuted "Wonder Years," which ran from 1988 to 1993 on ABC. His suit claims he was awarded "bonuses" for at least 66 episodes produced and distributed while he was president, the piece notes.

The lawsuit alleges that Fox acknowledged his rights and paid him the bonuses when "Wonder Years" was sold to networks including ABC Family and Nickelodeon. But the suit claims Fox refused to pay when the series was sold in 2010 to cable network The Hub.

Damages aren’t specified in the suit, and Fox wasn’t immediately available for a comment, according to the piece.
