The 2 nude photos that have been posted repeatedly in this thread are considered fakes by Joan Crawford aficionados.
That Joan Crawford made porno films and was in "The Casting Couch" is nothing but a rumor and Wikipedia doesn't say anything but that.

Joan Crawford "made some sex films back in the Twenties, most notably a silent one-reeler tantalisingly entitled 'The Casting Couch'. It is alleged that after she became famous MGM shelled out over half a million dollars in an attempt to buy up every surviving copy of the film. When one possessor of some nude shots refused to part with them, his house was burned down three weeks later, himself being a casualty as well as the pics."

David Bret's book "Joan Crawford: Hollywood Martyr" is riddled with incorrect facts and even has incorrect names for those who starred in major films of the era. Brett has no credibility whartsoever with any film historian and this is but one of several sensationalistic books written by him. One of his many allegations is that virtually all of the men in Hollywood during the first half of the 20th century were either gay or bisexual. One can not be sued for libeling the dead and Brett likely picked this group for the very reason that they are dead plus death makes it hard for them to defend themselves. Likewise, Joan Crawford has been dead for decades.
I do not mean to imply I know whether Ms. Crawford did porno or ever posed nude. She could be totally unscrupulous and had many sexual affairs. However, I would suggest taking the alleged films and alleged photos with a grain of salt.
