Marc Blake is a script consultant, writer and teacher of writing for sitcom. In this book he acts as a `script mechanic'' for writers - stripping a sitcom down to its component parts, isolating the faults and fixing them. What script editors and producers are looking for are scripts that work. Naturally they want a genius in embryo, but above all they first want to see something that is roadworthy.
