There's a very interesting description of a visit to the set of the
Survivors remake at
Total Sci-Fi. Sounds like they pretty much got the free run of the set.
I'm concerned though by these comments from Adrian Hodges:
"In some ways we feel that we've barely begun with Survivors, but in other ways I have to accept that this might be its final series ..... What I've tried to do with this series is give a satisfying conclusion so that if it proves to be the last episode, at least it will feel like a series that has finished in an appropriate way, but at the same time, almost every door is left open."Let's just hope he's wrong and we do get a S3!
