The trailer looks cool. I like this quote from the interview:

We decided to shoot everything green screen because we felt that the biggest enemy of believability visually is direct contrast – as an example, when Cary Grant gets into his car in a wide shot and then you cut to a driving close up which is shot in studio using back projection – the cut is jarring and takes you out of the film - the fakeness of the close up reminds you of the artificiality of it all. If on the other hand the whole film is back projection, then you just assume it is the look of the piece.

CGC: What kind of equipment was used for the project?

James: Essentially a bunch of computers were used running 3D max version 5 and After Effects…

The computers themselves were generally standard desktops (my main unit was, would you believe a 1.2GHZ mini-tower) – and the render farm was twin 2.8 GHZ towers with no monitors or frills to speak of all connected to a network using a standard hub - a pretty simple setup. Then we just got ourselves a couple of big portable hard drives ([300GB]) to transport the files around. That was pretty much that. Backburner (Max network renderer) performed very well. The system was so hot though that we brought in fans and a cooler. For a while the system heated the house.
