Robin Williams’ children post heartwarming messages on the eighth anniversary of the star’s death

Robin Williams' children have posted messages about their late father on the eighth anniversary of the film star's death.

Son Zak Williams paid tribute to his actor and comedian dad, who died by suicide in 2014, at the age of 63.

"Dad, on the eighth anniversary of your passing, I'm remembering how incredibly kind and joyful you were," the mental health advocate wrote on Twitter.

"I deeply miss you, you wonderful, hairy man and will be celebrating your life today."

The 39-year-old added: "Love you so, so much."

Williams' daughter Zelda also shared a quote online on the anniversary of her fathers death.

She also shared an array of links to suicide prevention hotlines around the globe.

"And once the storm is over, you won’t remember how you made it through, how you managed to survive, you won’t even be sure, whether the storm is really over," Zelda posted on social media.

"But one thing is certain. When you come out of the storm, you won’t be the same person who walked in. - Haruki Murakami."

As well as leaving behind his family, the star also left the world with an impressive legacy of work.

Whether he made you laugh as the iconic blue Genie in Aladdin, made you teary in Mrs. Doubtfire, or made you sit back and think in Good Will Hunting, his ability to make an audience feel was a rare talent.

Williams had struggled with alcohol and drugs early in his career, turning to substances to cope with the pressure of comedy.

But his time on the comedy circuit led to his breakthrough role as alien Mork on an episode of Happy Days in 1978.

From that, the spin-off show Mork & Mindy was born, in which he starred alongside Pam Dawber.

The rest, as they say, is history. From then on he became one of Hollywood's biggest stars.

After Williams' death in 2014, his family revealed the actor had been living with an undetected health condition called Lewy body dementia, which is a neurodegenerative disorder.

The condition - which can often be misdiagnosed as Alzheimer's or Parkinson's disease - can cause hallucinations as well as problems with understanding, thinking and memory.

Months before his passing, he'd been diagnosed with Parkinson's and it has been previously reported he had feelings of paranoia on the run up to his death.

Williams' disorder was only discovered during his 2014 autopsy.
