Doctor Who Trailer

I used a slow build up starting with sad music and a shot of Billy Piper crying to build up the emotion, then i sped up the music using Action music to speed up the pace, I then used another scene of the doctor and the Billy to show more emotion and finished with sinister music and a shot of one of the monster then blacked out to the sound effect of the darlecks to end on a slight cliff hanger, making the audience want to watch more. I had to find scenes which showed the same doctor to keep the continuity of the trailer going. I made sure I sped up the pace towards the end to build up to the climax and used faster music
