The documentary film also rose as a commercial genre for perhaps the first time, with the success of films such as March of the Penguins and Michael Moore's Bowling for Columbine and Fahrenheit 9/11. A new genre was created with Martin Kunert andEric Manes' Voices of Iraq, when 150 inexpensive DV cameras were distributed across Iraq, transforming ordinary people into collaborative filmmakers. The success of Gladiator lead to a revival of interest in epic cinema, and Moulin Rouge! renewed interest in musical cinema. Home theatre systems became increasingly sophisticated, as did some of the special edition DVDsdesigned to be shown on them. The Lord of the Rings trilogy was released on DVD in both the theatrical version and in a special extended version intended only for home cinema audiences.
There is a growing problem of digital distribution to be overcome with regards to expiration of copyrights, content security, and enforcing copyright. There is higher compression for films, and Moore's law allows for increasingly cheaper technology.
More films were also being released simultaneously to IMAX cinema, the first was in 2002's Disney animation Treasure Planet; and the first live action was in 2003's The Matrix Revolutions and a re-release of The Matrix Reloaded. Later in the decade, The Dark Knight was the first major feature film to have been at least partially shot in IMAX technology.
There has been an increasing globalization of cinema during this decade, with foreign-language films gaining popularity in English-speaking markets. Examples of such films include Crouching Tiger, Hidden Dragon (Mandarin), Amelie (French), Lagaan (Hindi), Spirited Away (Japanese), City of God (Portuguese), The Passion of the Christ(Aramaic), Apocalypto (Mayan), Slumdog Millionaire (a third in Hindi), and Inglourious Basterds (multiple languages).
Recently there has been a revival in 3D film popularity the first being James Cameron's Ghosts of the Abyss which was released as the first full-length 3-D IMAX feature filmed with the Reality Camera System. This camera system used the latest HD video cameras, not film, and was built for Cameron by Emmy nominated Director of Photography Vince Pace, to his specifications. The same camera system was used to film Spy Kids 3D: Game Over (2003), Aliens of the Deep IMAX (2005), and The Adventures of Sharkboy and Lavagirl in 3-D (2005).
As of 2010, 3D movies are gaining increasing popularity. After James Cameron's 3D movie Avatar became the highest-grossing film of all time, many other movies have followed suit and been released in 3D, with the best critical and financial successes being in the field of feature film animation such as DreamWorks Animation's How To Train Your Dragon and Walt Disney Pictures/Pixar's Toy Story 3.
