Neighbours from Hollywood
Belushi has accused Newmar, who played Catwoman in the 1960s Batman television series, of damaging his property.
In a lawsuit he claimed the former super-villain had launched a campaign of harassment aimed at driving him from his Los Angeles home.
Belushi starred in a number of films in the 1980s including K9 and Red Heat. He has since forged a successful television career.
He claims Newmar also badmouthed him to his other neighbours.
The 50-year-old is seeking a court injunction and $4 million in damages.
