Be that is any form it might take, not necessarily another television series; is the opportunity passed? If I remember, this was the year the copyright would have to be renewed to continue it.
Chris and Laura were working on a TLR comic book, but it seems to have fallen through. I can't imagine any way the series will resume. It would have to be done by the original writers, or it would not be The Lost Room. I just can't see them making any more heroic efforts to keep the concept alive.
