He's been working on this for years, but I think the hold up has been financing. Hopefully the project has moved forward again. I think the original intnetion was to do new imaged to original soundtrack but I think GA nixed that idea in favour of all new. Hopefully it will be a notch up from the Dan Dare series (which again played too loose and fast with the DD legend and even failed to credit Frank Hampson, but that's nothing new).
GA apparently has a fondness for CS, saying it was his "darkest"puppet show. Me, I'd like to see him do a "UFO" movie.
That series rocked!
