From a crossing dressing father in Mrs Doubtfire to an unorthodox therapist in Good Will Hunting, Robin Williams, brought humour and pathos to every role he played.
Well known as the quirky alien on the hit TV show Mork and Mindy, his first major success on the big screen came with 1987's Good Morning Vietnam.
His energetic portrayal of an offbeat DJ on Armed Forces radio won him the first of four Oscar nominations.
Another nomination would follow two years later for his role as the unconventional teacher John Keating in Dead Poets Society. A third soon followed in 1991 his role in The Fisher King.
Showing his remarkable versatility he went on to delight millions of children across the globe, first as the voice of the Genie in the Disney classic Aladdin and later as a dad who dressed up as a nanny, complete with a latex mask and a Scottish accent to spend time with his young kids.
It was his 1997 role as Matt Damon's mentor in Good Will Hunting that finally secured him a Best Supporting Actor Oscar.
From their he took on a variety of film and television roles, making notable performances in Night at the Museum. A third sequel featuring him is currently in post production.
He also voiced Ramon in the Happy Feet movies and played Henry Altman in the Angriest Man in Brooklyn, released this year.
Whatever the role, Williams would make it his own and his fellow actors were quick to pay tribute to both his acting abilities and personality.
Among them was Kevin Spacey, who was in the 2009 film Shrink alongside Williams.
He tweeted: "Robin Williams made the world laugh & think. I will remember & honor that. A great man, artist and friend. I will miss him beyond measureobin Will
