When Robin Williams died last year, a sequel to one of his biggest hits, Mrs Doubtfire, was in early development. As we've seen in recent times, an actor's untimely death, no matter how tragic the circumstances, doesn't necessarily mean curtains for a production.
CGI was used to finish Oliver Reed's scenes in Gladiator when he died of a heart attack halfway through filming, and the forthcoming Fast & Furious 7 used special effects to complete Paul Walker's scenes after he was killed in a car crash.
But Mrs Doubtfire 2 will never make it to the big screen after documents from Williams' estate emerged stipulating a restriction on his image, or any likeness of it, being used for 25 years after his death.
The filed deed states that his image cannot be used in film or publicity until 2039 and he also passed the rights to his name, photograph and signature to the Windfall Foundation, a charity that he set up.
