Flash animation production is enjoying considerable popularity in major animation studios around the world, as animators take advantage of the software's ability to organize a large number of assets (such as characters, scenes, movements, and props) for later re-use. Because Flash files are in vector file format, they can be used to transfer animation to 35 mm film without any compromise in image quality. This feature is used by several independent animators world-wide, including Phil Nibbelink, who saw his 77-minute feature film Romeo & Juliet: Sealed with a Kiss released in theaters in 2006. For Disneyland's 50 Magical Years film featuring Live action Steve Martin interacting with Donald Duck, the hand drawn animation of Donald Duck was cleaned up and colored in Flash.
