SEATTLE (AP) _ ``Science Guy'' Bill Nye is suing Disney.

The television personality says the company owes him more than half a million dollars for using his likeness on attractions at EPCOT Center.

Nye said Disney agreed to pay him $50,000 a year, starting in 1994. He said the company paid him $100,000 for hosting the opening of some exhibits at the Florida theme park but never made the royalty payments.

The suit was filed last week in U.S. District Court.

A Disney spokesman said the company does not comment on pending lawsuits.
