There are many supposedly great films that never made the final cut.
One of the most ambitious projects was the failed film adaptation by director Alejandro Jodorowsky of the 1965 sci-fi novel Dune, written by Frank Herbert.
Although David Lynch eventually made his own version of the book in 1984, there is now a documentary looking at Jodorowsky's efforts to bring the book to the screen in the 1970s.
Talking Movies' Tom Brook went to interview the director of Jodorowsky's Dune.
