I'm not generally a reader of bios, but I'm halfway through John Cleese's (partial) auto-biography SO, ANYWAY. I love Python so it's interesting to read about the development of his interests and honing of his abilities, plus it's cool to discover the inspirations for notable routines. It's neither riveting nor hilarious, rather an amusing look at Cleese's pre-Python years. There are certainly several funny bits, such as his anecdote of a sensitive friend's attempt to mercy-kill a sick rabbit, which is funny because it's so awful.
Of particular interest to me are the things he's learned about performing (energy levels of musical numbers vs stand-up routines in a variety show), writing (don't try to come up with the perfect punchline, find one that's good enough and move on), work (some days will see zero creative output, others will produce lots of good work, so it averages out to an acceptable level of work), and the comedy genre (futile anger, a la Basil Fawlty, is funny, while effective anger is not.) I wonder if I'm more receptive to learning via the tales of an interesting person than through standard texts.
To that end, can anyone recommend a similar book (biography or not) by someone in the horror field? I've read King's ON WRITING, so I'm looking for others. Also looking for good general non-fiction about the horror genre.
