Moon is an independent film about a lone engineer on a lunar mining station who learns that things are not as they seem as the end of his three-year term draws near. The director decided to rely heavily on miniatures instead of digital effects for the film, enlisting the talents of Bill Pearson (perhaps best known for his work on Alien). Here is a detailed post from the VFX supervisor on the film that provides some great background info and model shop photos.
Bonus: If you've not yet seen the film and have access to Netflix, it is currently available for streaming (Dec. 2010).
