Most major movies out there are filled with special effects in all kinds of forms. It might be a fully computer generated character, it my big a massive spaceship above New York, but one of the most iconic methods is matte painting and landscape design.
It's been used since the early days of cinema, and until this day it will be on screen and you don't even know it. Jadrien Cousens is a very talented landscape artist with amazing pieces in this field. Here are some of his work. For more of it and to check some of the films he has worked on, please check his DeviantART and personal site. I hope you enjoy these! Cheers. ;)
