This is very exciting. I'm really not a fan of And Another Thing..., but Dirk Maggs did well with the last three series and cleaned up Dirk Gently for radio too. Hopefully, there will be more of Adams' original material and less of Eoin Colfer's, but it's exciting all the same.
It's also so sad that Susan Sheridan has passed, as she was the best Trillian, but Sandra Dickinson will do her justice as a 'blonder, more American' Trillian. Stephen Fry would've been great as the Book, but I suppose he's out of their price range...
