Looking for film/tv show: sudden relocation



The first part of the film (or tv drama) that I am looking for information about, is the story of the (boring) life of a normal family man (in England?) Then one day he wakes up in some kind of dome/house on another planet. There is a disembodied voice that he can talk to that tells him that he has always been there. Thats all I can remember.

Does this ring any bells with anyone? Made sometime between 1980 - 2000 I guess. I thought Peter Firth was the lead, but I've looked through his stuff at IMDB and can't find anything. I'm 99% certain I haven't imagined this, but its getting to the point that if I can't find any evidence of something existing on the internet, I believe the internet and doubt my own memory. (Maybe there's a story in there somewhere).
