1. That the intensity of Laine Megaw's performance as Sandra is enhanced by the fact that in real life she is married to Stuart Graham, the actor playing her screen husband, Kyle.
''I like working with Stuart,'' she laughs. ''We have a wealth of experience together which we can turn into a screen relationship. There's a bond and electricity there which we can draw on. People are very leery about casting us together because they think we're going to have domestics all over the place, but we never do. I get very passionate in the rehearsal room. I'll have arguments with everyone except Stuart because I can argue with him when I get home. The great thing is, we've been married for nine years but we still get on!''

6. The film was critically acclaimed at the 2001 Edinburgh Film Festival. ''The reviewers were absolutely gripped by it,'' the director Harry Bradbeer recalls. ''Even the projectionist stayed to watch it which is most unusual. Normally, they sit there reading the paper and having a fag.''
7. As The Beast Sleeps has been a huge hit on the festival circuit. It received its world premiere at this year's Edinburgh Film Festival - a prestigious achievement for a low budget TV single.
