Bill Nye filed a $37 million lawsuit against the Walt Disney Company and a number of its subsidiaries on Thursday, alleging that he was deprived of $9 million in profits from his show, “Bill Nye the Science Guy,” which originally ran from 1993 to 1998 on PBS.

He also said that the defendants profited off his work to the tune of more than $28 million. The defendants also include Buena Vista Television and ABC, the show’s distributors.

A spokesperson for Buena Vista Television said in a statement: “This lawsuit is a publicity ploy and we look forward to vigorously defending it.”

The lawsuit’s assertions include fraudulent concealment (that Disney and its subsidiaries knew of profits from the show that they kept from Mr. Nye), breach of contract and breach of fiduciary duty.
