I was just reading "The Remarkable Michael Reeves: His Short and Tragic Life" by John B. Murray. Reeves was approached by American International Pictures to direct a Richard Matheson script titled "Implosion". It was about the life of the Marquis De Sade and absolutely brilliant. Orson Welles got a hold of the script and wanted to direct it himself. His old friend and colleague John Huston was cast as De Sade's libertine uncle.
Reeves was deeply troubled. He found "Implosion" too disturbing and turned it down. He would never direct a picture again, committing suicide in February 1969. The script went through several rewrites and was retitled "De Sade." In the process, it was utterly ruined, according to Matheson, who retains credit for the screenplay of "De Sade", which was eventually directed by Cy Enfield. Roger Corman directed the sex scenes when Enfield proved unwilling or unable to do so, due to his Puritanical nature. "De Sade" was a disaster, with a fatally miscast Keir Dullea in the title role.
According to Murray, this has to go down as one of the great lost opportunities in the history of the cinema. It would be great if "Implosion" were published. Matheson is a master of the macabre, one of the great horror writers of the post-WW2 era.
