Of all my films, 'The Dark Coat' has received the most speculation that it would be a great feature. I even did a sequel, 'Giallo'.
Others that made the list; 'When Last Seen Alive', 'Podcast', 'The Things They Leave Behind’ and 'Please Stand By'.
One I'd personally add is 'The Apartment at the End of the Hall'.
I don't know what the next one will be, but 'On A Dark and Stormy Night' seems to be a leading contender.
