Preview

Preview performance refers to a showing of a film to a select audience, usually for the purposes of corporate promotions, before the public film premiere itself. Previews are sometimes used to judge audience reaction, which if unexpectedly negative, may result in recutting or even refilming certain sections based on the audience response. One example of a film that was changed after a negative response from the test screening is 1982's First Blood. After the test audience responded very negatively to the death of protagonist John Rambo, a Vietnam veteran, at the end of the film, the company wrote and re-shot a new ending in which the character survives.
