Historical Context

Over time the quality of cinema viewing has enhanced, with the obvious improvement of conditions and screening quality. Also, the quality of picture has improved, with digital technology seeing changes in the way we see films today - one notable change being the use of technicolour rather than black and white films. Recently, films have become increasingly interactive, with the use of 3D effects the audience feel as thought the characters, and often objects, can reach out and touch them. One director, James Cameron, has gone to lengths to take this interaction further by changing the face of cinema today. His latest film, set to release 17Th December 2009, Avatar uses 3D CGI technology so the audience can feel themselves inside the movie, right beside the characters and action.
Trailers have evolved also, moving from their rightful place at 'the back', as depicted in the name, to becoming a preview of what is to come. They have come far from moving pictures and text, now involving sound and a wide variety of scenes from the film to entice the audience. They incorporate the best snippets with music, in action comedies that music is often playful, to help hammer home the point of the film. They also introduce directors, titles and certificate at the end of each trailer so the audience knows whose work it is. All of which has developed over time.
