A "lost" movie by cult US film-maker Ed Wood is to be released for the first time this week.
Depp played Wood in a Tim Burton film
Necromania, Wood's last film from 1971, was made for about $7,000 (£3,800) and went missing shortly afterwards.
The pornographic movie is about the sexual enlightenment of a young couple at the hands of a coven of witches.
Wood, often called "the worst film-maker of all time", was the subject of Tim Burton's 1994 biopic in which he was played by Johnny Depp.
That film shows the making of Wood's most famous film, Plan 9 From Outer Space from 1956, in which actors mess up their lines and special effects include pie tins for flying saucers.
Necromania was unearthed by Ed Wood enthusiasts Alexander Kogan and Rudolph Grey in a warehouse in Los Angeles after more than 15 years of detective work.
"This is something more than just porn," said Fredrik
Carlstrom, executive producer of the DVD, which is being sold this week.
"It has a story, it has ambition. It's like all his
films, like anything that's so bad it becomes good. Or maybe it's pure genius. That's the appeal of Ed Wood."
