Não se esqueça de que o marketing pode começar em um filme muito antes de uma impressão final ser concluída para distribuição teatral. Muitas vezes, os editores terão acesso a TODAS as filmagens ao cortar um trailer, às vezes apenas seqüências específicas. É um esforço colaborativo em que eles aprovam tudo o que é usado, mas é por isso que takes alternativos ou até mesmo piadas são usados em trailers. Porque na época, pode não ter havido um final criado.
Trailers tell the story of a film in a highly condensed fashion that must have maximum appeal. In the decades since film marketing has become a large industry, trailers have become highly polished pieces of advertising, able to present even poor movies in an attractive light. Some of the elements common to many trailers are listed below. Trailers are typically made up of scenes from the film they are promoting, but sometimes contain deleted scenes from the film.
Most trailers have a three-act structure similar to a full feature-length film. They start with a beginning (act 1) that lays out the premise of the story. The middle (act 2) drives the story further and usually ends with a dramatic climax. Act 3 usually features a strong piece of "signature music" (either a recognizable song or a powerful, sweeping orchestral piece). This last act often consists of a visual montage of powerful and emotional moments of the film and may also contain a cast run if there are noteworthy stars that could help sell the movie.
Some trailers use "special shoot" footage, which is material that has been created specifically for advertising purposes and does not appear in the actual film. The most notable film to use this technique was Terminator 2: Judgment Day, whose trailer featured an elaborate special effect scene of a T-800 Terminator being assembled in a factory that was never intended to be in the film itself.
Então, isso pode ser o mesmo para o caso do The Amazing Spider-man ou < O trailer de Dark Knight Rises contém algumas cenas deletadas.
