It's been almost 20 years since Charlie's Angels went off the air and actor John Forsythe still hasn't met two of the actresses who played his crime-fighting Angels on the show.

Forsythe, who provided the disembodied voice of boss Charlie Townsend over a speakerphone throughout the show's five-year run, says he has yet to meet former Angels Shelley Hack and Tanya Roberts. Of course, meeting his co-stars was never easy, given that he recorded his lines at an audio studio and was never on the set.

Over the years, the actor has met the four other actresses who played his Angels, according to a new book on the series, Charlie's Angels Casebook, by Jack Condon and David Hofstede (Pomegranate Press). He co-starred with Jaclyn Smith in the 1978 TV-movie The Users; he happened to meet Kate Jackson at Santa Anita Park racetrack; he eventually became neighbors with Cheryl Ladd, and he once bumped into Farrah Fawcett-Majors at the tennis courts.

"I was coming off the court when she came up to me and said, 'Charlie! I finally met Charlie!' " recalls Forsythe.

According to the book, Forsythe was offered the Charlie role in a panicky late-night phone call from producer Aaron Spelling after the original choice, late actor Gig Young, showed up too drunk to read his lines. "I didn't even take my pajamas off ? I just put on my topcoat and drove over to Fox," Forsythe recalls. "When it was finished, Aaron said, 'That's perfect.' And I went home and went back to bed."
