Pseudo-documentary
A pseudo-documentary is a film or video production that takes the form or style of a documentary film but does not portray real events. Rather, scripted and fictional elements are used to tell the story. The pseudo-documentary, unlike the related mockumentary, is not always intended as satire or humor. It may use documentary camera techniques but with fabricated sets, actors, or situations, and it may use digital effects to alter the filmed scene or even create a wholly synthetic scene.
