As someone for whom Kubrick's films represent a kind of fixed stars in the cinematic universe and who has already read a lot about Kubrick, this was a truly insightful read.
The book consists mainly of pieces which have already been published before, but also some new ones. Although they touch on many subjects, there is one central theme that connects most of them – that Kubrick's image in popular culture – that of a misanthropic, half crazy hermit who controlled everyone and everything – has little foundation in reality. Ulivieri, who makes heavy use of archive material, traces the origin of what he calls the «Kubrick Mythology» and comes to a surprising conclusion: The mythology was at least partly a creation of Kubrick himself who not only wanted to have complete control over his movies, but also over his own image in order to publicise his movies better.
Obviously, this again reinforces the Kubrick Mythology to some degree; Kubrick is such a control freak that he even controls how he appears to the public – a fact of which Ulivieri is well aware. Still, it's interesting to see, that early on, Kubrick was very strategic when it came to present himself in a certain way in interviews and press releases, and that the image of a genius and control freak suited his needs quite well.
What I found particularly fascinating is that, according to Ulivieri, Kubrick's "PR campaign" also included how he was perceived in academia. One goal of the of the PR for 2001 was to elevate its director to a higher sphere of cinematic genius. To accomplish this, Kubrick closely collaborated with Alexander Walker who wrote the first monograph on the director and was arguably instrumental in turning Kubrick into an 'auteur'. At the same time, Kubrick blocked the publication of another, less referential book by Neil Hornick.
I don't think I've ever heard of another director doing this (certainly not as early as the late 1960s), and I think it adds another layer to the whole discussion about the 'auteur' (which is a problematic concept anyway).
«Cracking the Kube» also shows fandom it its best. Ulivieri is not an academic but a fan who has read everything related to Kubrick, talked to everyone who met him, and basically knows more about Kubrick than any living creature. Still, he is not a fanboy and also not into presenting sensational anecdotes. He is rather interested in how Kubrick worked, in his MO, and he backs up everything he writes with sources.
