During the movie we have a lot of scenes set around our alien pods. We are initially introduced to them when our heroes discover them attached to the base of the harvester ships which attack the cities. Then we see them inside the huge mother-ship which orbits the Earth.
When we see them in wider shots, for example, hanging from the ships, these will mainly be computer generated (as in the photograph). But as there are a lot of shots where we see them in close up and people need to interact with them, we felt it important to actually get some built. Ideally, we would like to have four of them made as they appear in a pod circle that our lead actors will need to work around, however, at £2,500 per pod, we probably won't be able to afford to do this. So we'll need to be clever when we film these scenes and move the pod around per shot.
The pod has been designed many times and originally they were more machine like (as in Matt Allsopp's picture below). These worked great when built in CG, but to get them made practically would have been very expensive and they would have been more difficult to film.
Eventually, we decided to go with Henry Strong's more organic design, which we feel works very well. Do let us know what you think!
