This weird UFO of a movie that didn't belong in the Eighties. It was ahead of its time and a little bit obsolete at the same time because it was done… - Louis Leterrier

My challenge was working with puppets, but their challenge was working with Louis Leterrier. I was non-compromising, "this will not look like your grandfather's puppet show, and this will look like The Dark Crystal, that broke the mould then, so let's break it again and bring puppetry as far as it can get", and that's really what we did.

We just enhance the eyes, a quiver of the mouth, the eyes fluttering a little bit, glossing over. But it's still the glass eye of the puppet, it's still the skin of the puppet, we move it just slightly, and that made a huge difference. The limits I set were that it cannot be better than what you could do with an amazing animatronic puppet with lots of motors and stuff.

[T]here was a whole bunch of elaborated ideas from Jim Henson and Frank Oz, the story that led to the movie, and that stuff was so interesting to me that eventually I was like, you know what? I'd like to take a look at what happened before the movie. It's such a big canvas that it might not even be a movie, it might be a series.
