Verbatim from an Amazon.com review:
Alfonso Dupont said:
We true insiders know that the original Star Wars movies were made at a time of turmoil in Hollywood, when mob assassinations and drug-fueled orgies were a fact of life on every film set. It is believed that it was at a swinger party where Marcia Lucas was successfully wooed from her Jedi Knight husband by a shadowy plumber. The ugly divorce almost drove George insane, and only by immersing himself in the world of puppet Salacious B. Crumb--even at one point claiming he would play the character himself--was George able to weather this turbulant period.
This was of course followed by what film historians now know as the "sham years", when George Lucas dated several famous women in public (and even once gave his penile size in an interview), but in private drifted into homosexual experimentation. Part of this is hinted at in the George Lucas Usenet Archive, a collection of George's posts to an Internet forum of some kind, written during the making of his "prequel trilogy".
Many film historians have heard the stories of what went on behind and in front of the camera, including impromptu sex scenes that were removed from the final edits and a bloody quarrel between Mark Hamill and Sir Alec Guinness that involved accusations of rape. Oftentimes a cover story was used to explain why certain footage had "disappeared"--for example, at the top of the frame in the original Jabba scene was visible both a bobbing boom mike and a crew member's bobbing, fleshy organ. This was later explained as the scene being cut because of difficult special effects.
If this is all true, I am terrified!
