I think DNA was an incredible writer, but frustratingly unprolific. There's some interesting stuff in this book about him trying to get the Hitch-Hikers movie made. At one point he was told by studio bosses that they didn't think there was any demand for 'science-fiction comedy'. Shortly thereafter we got Ghostbusters and some time after that Men In Black. (Also a bunch of Star Wars movies - not deliberately funny but hey). It's a tragedy that the movie that was eventually made was so naff, almost as bad in its own way as the appalling BBC TV version. Sheesh.
Elsewhere in the book he raves about the Beatles, comparing them very favourably to J.S. Bach. And coincidentally it's the somethingth anniversary of the Beatles doing something, and I've been listening to Sgt Pepper's all day. Fantastic stuff indeed.
