The 16th scene we filmed, and the 16th scene shown in the movie. Hooray for coincidence!

We spent a bit of time sorting out how to get the hard shadow across Neo's face, as this is obviously an important aspect of the scene. We had the agent mounted on a hinge so we could raise and lower his shadow over Neo, and animated it by hand.

In order to get the lighting right we had to move the set into a different room. To make things easy for ourselves we used a big grey baseplate instead of our original set. This was, on reflection, a mistake as they are quite different, especially when the baseplate doesn't have the Lego logo on each of the studs.

Another important tip we can offer here is to not build your set on top of the box with all the Lego in it!
