It was as if we'd never stopped, really. It took an hour around those lovely friendly faces to feel like we'd never left.

Was it difficult working on a show with so much CGI?

Look, it's an actor's job to imagine things, no matter what.

The timeline from the idea being born to ending up on the Sci Fi Channel was pretty fast, and because of the CGI component we did have to deliver things sooner rather than later. That was the major consideration with CGI, they need time.

We could not have made the show without Ben, that's for starters, and had he and I not got on, I don't know if anyone would have really wanted to turn up for work every day.
