I never saw it, but apparently he made a cinema ad for "Roofworld" when it was first released. I think that's the greatest prominence anything of his has had on the silver screen

. There's a "download" section "Coming Soon" on
http://www.christopherfowler.co.uk/pages/home/home.html - as it was his firm that made the ad, maybe it will go up there.
According to the website, a lot of the books have been optioned, but none seem likely to come to fruition. The 2 that sounded most likely to be made were Spanky (but Guillermo del Toro, who was due to do it seems to have a full slate) and Psychoville (but as Natural Nylon has collapsed - and I don't think Jude Law and Sadie Frost, the putative stars, are talking - this seems unlikely).
I've not seen them, but apparently the following short stories have been filmed: "The Master Builder" (as "Through the Eyes of a Killer" with Marg Helgenberger, Richard Dean Anderson and Joey Pants) for US TV; "Left Hand Drive" won Best British Short Film in '93 and played cinemas and Channel 4; "On Edge", another short, allegedly also had a limited cinema release and features Doug "Pinhead" Bradley, Charley Boorman and some guy called Christopher Fowler

; "The Most Boring Woman in the World" is another short.
