Saxon Logan's horror film Sleepwalker has just been confirmed as the next Flipside release, out in September.
IMDB entry here, and considerably more background info here - its Flipside credentials are more than established by the fact that it's barely been seen since its completion in 1985.
I assume, given the 50-minute running time, that there'll be more films in the package.
UPDATE: There will be!
BFI FLIPSIDE PRESENTS
A film by Saxon Logan
When wealthy couple Richard and Angela visit Marion and Alex in their decaying family home, their differing social and moral attitudes create uneasy tensions. An inharmonious evening of drunkenness and sexual rivalry soon turns bloody as the guests fall victim to an unhinged attacker.
Featuring a rare performance from Bill Douglas (Bill Douglas Trilogy, Comrades), and starring British screen greats Joanna David and Heather Page (both of whom would go on to work with Douglas in Comrades), Sleepwalker is an outrageous and incendiary mix of biting satire and bloody horror that is at once reminiscent of otherwise unlikely bedfellows Lindsay Anderson and Dario Argento. The stellar cast also includes Nikolas Grace, and features cameos by Fulton MacKay, Michael Medwin and Raymond Huntley.
Remastered from the only surviving print, this long-unseen mid-length film is presented here for the first time on any home video format, along with two shorts by its director, Saxon Logan, and the rare 1971 mid-length fantasy, The Insomniac, directed by Rodney Giesler.
• Presented in High Definition and Standard Definition
• The Insomniac (Rodney Giesler, 1971, 45 mins): a man experiences a night-time world that is part foreboding nightmare, part sexual fantasy
