OK, I taped this off TV and missed the very start. The film was about 10 or so seconds into the titles (I assume) so if anything happened before that I missed it.Lots of people say Mark Hammill is in this, I didn't see him. I did recognise Clive Barker, John Landis and obviously Stephen King doing some really awful acting as the graveyard attendant.Alice Krige looks lovely apart from the scenes where she has the cat face or is in full alien make-up.Even with the opening titles it's never really explained very well exactly what Sleepwalkers are or where they come from. From the title sequence I assume they are catlike bipeds who live by extracting life-force from humans. I assume they live a long time and these particular 2 are possibly the last of their kind.Add to this a very large dose of incest (Yes! I thought it was a bit suspect too), shapeshifting, killer cats and invisibility and you have Sleepwalkers.It's a very bad story that has no real explanations behind the main 2 characters and far too many cameo's to try and distract from the simple fact that not enough is explained to the viewer.Avoid.
