Up until a few months ago the only DVD companies I really rated for horror fans were Anchor Bay and Blue Underground but it's good that the more obscure exploitation and giallo films are getting a lease of life. The sleazy aspect of the pictures and the bright yellow cover helps them stand out, as posters these days are too generic and lack appeal. Up until the eighties, they used to be outrageous and try to top the last film, but since Scream horror posters seem content with just showing close up headshots of the actors. So the approach you've taken has given customers an alternative, something a little more retro and raw. That is something to be proud of!
Just posted an article on Night Train Murders if you're interested, it's in the new column I'm doing on giallo. You can check them at
