This is a graphic novel from Neil Gaiman and Dave McKean. A film director from London is dying from cancer. He refuses treatment - which looks hopeless anyway - and keeps working on his last movie (sorry, we are talking about Great Britain here, so it is a film he works on). There are actually two plot lines in here: the one about the dying guy and the one about the people who exist inside his mind as a part of the film.
There are some interesting ideas in here and the drawings are always top-notch. The only reason I gave this 3 stars only is that I have the feeling the subject of a dying artist creating a masterpiece has been done do death (sorry about the bad pun). Still it is worth reading at least once.
