Terry Gilliam, the US-born director famous for a string of dark fantasy films, has finally finished his version of Don Quixote... after 17 years battling one disaster after another.

"Sorry for the long silence...," he posted laconically to Facebook on Sunday.

"After 17 years, we have completed the shoot of THE MAN WHO KILLED DON QUIXOTE. Muchas gracias to all the team and believers. QUIXOTE VIVE!" (Quixote lives!)

Gilliam said he and his crew had just finished shooting in Spain. But it has been a long haul for the director of "Brazil" and "Twelve Monkeys".

Like the aging knight at the centre of Miguel de Cervantes' classic tale, Gilliam, now 76, has had to deal with one mishap after another to complete his quest.

His first tilt at adapting the 17th-century novel was with US star Johnny Depp and French actors Jean Rochefort and Vanessa Paradis.

That came to grief back in 2000, hit by a string of setbacks that included torrential rain and constant flyovers by military jets from a nearby NATO base.

To top it all, Rochefort, whose role as Quixote required riding a horse, developed back problems that put him out of action.

The new version features British actor Jonathan Pryce as Quixote. He starred in Gilliam's 1985 hit "Brazil", but is perhaps better known to younger viewers as the High Sparrow in the "Game of Thrones" television series.

Also on board is US actor Adam Driver, the villain in the latest Star Wars film; and the Ukrainian-born French actress Olga Kurylenko ("Quantum of Solace").

The history of Gilliam's disastrous first attempt to film his Quixote project has passed into film folklore: there is even a 2002 documentary, "Lost in La Mancha", that tells the whole sorry story.

Keith Fulton and Louis Pepe, originally hired to do a making-of film to accompany the finished product, finally managed to salvage an award-winning documentary from Gilliam's disastrous shoot.

But Gilliam, like the steadfast Quixote, refused to surrender.

The former member of the Monty Python team, and a specialist in absurd fantasies such "Jabberwocky" and "Time Bandits", pushed on with his project.

"Shooting my version of Don Quixote is a medical obligation," he told the Spanish daily El Pais last year. "It's a brain tumour I have to eradicate."
