Machinima can be less expensive than other forms of filmmaking. Strange Company produced its feature-length machinima film "BloodSpell" for less than £10,000. Before using machinima, Burnie Burns and Matt Hullum of Rooster Teeth Productions spent US$9,000 to produce a live-action independent film; in contrast, the four Xbox game consoles used to make "Red vs. Blue" in 2005 cost $600. The low cost caused a product manager for Electronic Arts to compare machinima to the low-budget independent film "The Blair Witch Project", without the need for cameras and actors. Because these are seen as low barriers to entry, machinima has been called a "democratization of filmmaking". Berkeley weighs increased participation and a blurred line between producer and consumer against concerns that game copyrights limit commercialization and growth of machinima.
