Movie star and former California Gov. Arnold Schwarzenegger says Republican presidential hopeful John Kasich is as unstoppable as a Terminator.

Campaigning with the Ohio governor in a telephone town hall on Friday night, Schwarzenegger compared Kasich to his most famous role as a cyborg assassin in the film "Terminator," according to WCPO Cincinnati.

He noted that the character in the 1984 movie doesn't feel pain and is practically unstoppable.

"This is you," he told Kasich. "You are the Terminator."

The actor contributed $2,700 to Kasich's campaign last year and has appeared at fundraisers for the Ohio governor, though he has not officially endorsed him.

Kasich, meanwhile, landed a celebrity endorsement this week in talk show host Montel Williams, who said in a USA Today op-ed that "we need an adult in the White House."
