The sad news of Robin Williams' death means the planned Mrs Doubtfire sequel is now unlikely to go ahead.
But the 63-year-old actor had a string of unreleased movies in the can before his suspected suicide.
Robin won a Golden Globe award for his starring role in 1993 Mrs Doubtfire, about an actor father who poses as a female housekeeper in order to spend time with his children after the break up of his marriage.
In April it was revealed the long mooted sequel had been resurrected by Fox 2000 with Robin attached to star, original director Chris Columbus on board and David Berenbaum, who penned 2003 movie Elf, writing the script, but this now looks in doubt.
Fans of the late comedy genius gathered at the house in San Francisco where the original movie was filmed to pay their respects and remember their favourite performances.
Among the many flowers and candles, fans laid photographs of Robin as Mrs Doubtfire and alien Mork from sitcom Mork & Mindy, as well as a sign bearing the words "Oh captain, my captain" from Dead Poets Society.
Robin was found hanged in his home in Tiburon, California, on Monday. He was discovered by his personal assistant after he failed to answer his door.
Folllowing news of the comedian's death, fans flocked to the house in Steiner Street in the Pacific Heights area of San Francisco that was used as the family home in the film.
One note on a bouquet of flowers read: "Thank you for a wonderful childhood with your many movies, you made our childhood much more enjoyable." Another said: "Our hearts are broken."
Films that Robin did complete before his death include The Angriest Man In Brooklyn, co-starring Peter Dinklage and Mila Kunis, about a man who is told he has just 90 minutes to live and make his peace with family. The movie had a limited release in the US in May but is yet to be shown in the UK.
He also reprised his role as Theodore Roosevelt in the third instalment of children's adventure Night At The Museum series, which is due for release just before Christmas.
And Robin voiced the part of dog Dennis in Monty Python star Terry Jones' upcoming comedy Absolutely Anything about a man granted omnipotence by a group of aliens. The Monty Python team voice the aliens while Simon Pegg stars as Dennis' owner.
Before he died, Robin also made Boulevard, which premiered at this year's Tribeca Film Festival, about a middle class bank employee forced to confront his marriage of convenience, romance The Face Of Love with Annette Bening and family road trip comedy Merry Friggin' Christmas.
Joel McHale who co-stars in Merry Friggin' Christmas tweeted about Williams, saying: "You were one of the very best that ever was. You were one of my heroes."
And the tributes have continued to flood in for the late, great actor and comedian.
Ben Affleck and Matt Damon who starred with Robin in their Oscar-winning debut Good Will Hunting both paid homage to him.
The film brought Williams his only Academy Award and launched the careers of Affleck and Damon.
Ben posted this on his Facebook page: "Heartbroken. Thanks chief - for your friendship and for what you gave the world. Robin had a ton of love in him. He personally did so much for so many people. He made Matt and my dreams come true.
"What do you owe a guy who does that? Everything. May you find peace my friend. #RobinWilliams."
And Matt released a statement saying, "Robin brought so much joy into my life and I will carry that joy with me forever. He was such a beautiful man. I was lucky to know him and I will never, ever forget him."
Sarah Michelle Gellar, 37, who played Robin's onscreen daughter in the short-lived CBS comedy The Crazy Ones, also joined the stars lining up to pay tribute to him
"My life is a better place because I knew Robin Williams," Sarah told People in a statement. "To my children he was Uncle Robin, to everyone he worked with, he was the best boss anyone had ever known, and to me he was not just an inspiration but he was the Father I had always dreamed of having. There are not enough adjectives to describe the light he was, to anyone that ever had the pleasure to meet him. I will miss him everyday, but I know the memory of him will live on. And to his family, I thank them for letting us know him and seeing the joy they brought him. Us crazy ones love you."
Billy Crystal and Whoopi Goldberg, who both worked with Robin on comedy fundraiser Comic Relief shared their heartbreak.
Billy tweeted: "No words", while Whoopi added on Twitter: "Billy Crystal is right... There are no words."
