Eritrea Movie “Sidra” (September 9, 2017)

Films are cultural artifacts created by specificcultures. They reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment, and a powerful medium foreducating—or indoctrinating—citizens. The visual basis of film gives it a universal power of communication. Some films have become popular worldwide attractions by usingdubbing or subtitles to translate the dialog into the language of the viewer. Some have criticized the film industry’s glorification of violence[2] and its potentially negative treatment of women.[3][4]

The individual images that make up a film are called frames. During projection of traditional films, a rotating shutter causes intervals of darkness as each frame, in turn, is moved into position to be projected, but the viewer does not notice the interruptions because of an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. The perception of motion is due to a psychological effect called phi phenomenon.
