Moon.

The film was created by Duncan Jones (son of David Bowie) and stars Sam Rockwell (hitch-hikers guide to the galaxy) and has Gerty, a robot voiced by Kevin Spacey (american beauty) who was only actually on set for half a day but obtained the highest pay. Originally Jones wanted Rockwell for another film but the role didn't suit him so they went their separate way until Jones came back to him with the script for moon

Moon had a relatively small budget of $5,000,000 (roughly £2,500,000) and in and effort to cut costs Jones cast very few actors as well as the whole thing being filmed in only 33 days In a london studio. The editing phase he cut corners to save money, He did this by using effects companies such as Cinesite who are notorious for their costs being cheaper than major effects companies, the film was independent so its small budget this was the only financially viable option. They also avoided sending any copies of the movie to the oscars as it costs money to print the dvds and they werent sure of the critical response from the judges.

Overall the film made  $9,747,108 worldwide with the  UK making a 5th of that. despite making a proit of £4.5 million, Jones is still attempting to pay his investors back because they want interest on the money they put in.
