Captain Quirk: The Unauthorized Biography of William Shatner is a curious 1995 biography written by paranormal investigator Dennis William Hauck. For the most part it is a perfectly decent biography, and despite the exploration of some negative sides to the actor, one senses a great affection for Shatner from the author.
On the other hand, the book's opening two chapters are consumed with Hauck's personal experience of working with Shatner in 1976's Mysteries of the Gods documentary. Mixed in with this are some truly idiotic deductions with regards to Shatner, UFO's, Star Trek, Gene Roddenberry etc. It is true that Shatner had claimed to have had a UFO experience in the California desert, although he later admitted he made it up. The author of the book not only explores this alleged encounter but then attributes a great deal of Shatner's later work to a personal quest to interpret this deeply moving experience. He also makes several very spurious deductions in this regard. Baloney. Shats went where the work was, simple as that.
Anyway, here is a quote from the book with regards to Shatner's (rather long) toup. The actor is interviewing a scientist on the roof of a COMSAT technical center and the author of Captain Quirk is present at the scene:
"Unfortunately, the bright sunlight made Shatner's long-haired toupee all the more obvious. The black hairpiece clashed against his blonde eyebrows and yellow jacket, giving him the appearance of a Beatle doll. His natural light-brown hair had steadily receded over the last decade. leaving a bald spot at the crown of his head. His efforts to cover it up were betrayed by his inability to decide on one style or color. This was the longest hairpiece he had ever worn, and the unkempt look and dark color were dead giveaways."
