Gentle Giant was actually mentioned in Playboy Magazine, albeit in the Ukrainian edition of the magazine. In the February 2007 issue, there was an interview with a Russian movie director, Pavel Ruminov, who is apparently a big fan of GG. He said in the interview that he would like to make a movie about the last year of GG's existence when they made Civilian and were about to dissolve the band.
The cover featured the Ukrainian pop singer, Fennix.
Thanks to GG fan Woon Deadn for tracking down this extremely obscure piece of trivia!
