Ben stiller

"I'm sad to say that my father passed away from natural causes," Ben wrote on Twitter, calling him "a great dad and grandfather" and "dedicated husband".

Jason Alexander, who played George on Seinfeld, called him "a great actor, a great man [and] a lovely friend".

Stiller spent many years in a comic duo with wife Anne Meara, who died in 2015.

His other roles included Arthur Spooner in TV sitcom The King of Queens.

Stiller appeared with son Ben in several film comedies, among them Zoolander, Zoolander 2 and The Heartbreak Kid.

The star of Zoolander was diagnosed with a tumour in 2014.

He says he now wants to share his story to lend his support for a controversial test which saved his life.

In an article on Medium, Stiller described the moment of his diagnosis as "a classic Walter White moment, except I was me, and no-one was filming anything at all".

He wrote: "I got diagnosed with prostate cancer Friday, June 13 2014. On September 17 of that year I got a test back telling me I was cancer free.
