Q: What is the origin of the Pan-Galactic Gargle Blaster, and how would you make one on Earth?
DNA: Unfortunately there are a number of environmental and weapons treaties and laws of physics which prevent one being mixed on Earth. Sorry.
Q: Did you ever think that you would be so successful, or that what you wrote would cause all of this?
DNA: Bzzz bzzz. Meaningless unanswerable question alert.
Q: All the women in DNA's books remind me either of the women in the Georgy Girl or the women in the movie Blowup .. coincidence or young adult infatuation with the Redgrave sisters?
DNA: This must be the single weirdest question I've been asked in twenty years.
From Memorable Questions and Answers with Douglas Adams.
And an interview with Nick Goldsmith (producer) and Garth Jennings (director) of the eagerly awaited (by this blog at least) Hitchhiker’s Guide to the Galaxy feature film, by MJ Simpson, author of Hitchhiker: A Biography of Douglas Adams, the site Magrathea, and “the world’s leading Douglasadamsologist” [The Observer] and Jim Lynn, editor of H2G2. From the sound of it, they won't Hollywood it too much. And finally there'll be a movie i'd happily wait in line for. Also see: this and this and this.
