A bloke Uruguay who put a short film up on youtube ended up getting a movie deal from sam Raimi of evil dead fame
The short shows a attack on a city by walker robots and sort of flying saucers and was apparantly made for about 300 quid.
The guys comment that if he can do it anyone can is somewhat misleading looking at the quality of the short film with it's wonderful attention to detail the near perfect motion matching shadows and lighting alignment as well as the environment being altered by the passage of the robots in water or on the tarmac making all the cgi elements fuse with the real world footage this sort of level of work is not something an amateur even a talented one could turn out.

It's very well done...as you say the attention to detail, and destruction of the buildings looks pretty good.
