Research & Planning: Documentary Film

This is a Film/documentary trailer, I find that the way the actual content is structured together as a documentary could prove useful when filming my trailer. At the start of this video it introduces what the program is going to be about, he is narrator of the video but is also starring in the film/documentary, I could use this in my documentary. When he introduces the documentary there is a shot of what the documentary is going to be based on, I could use this by putting a visual of the words 'ILLUMINATI' and the pictures that are linked with the illuminati.
Within this documentary film there is archived footage which I could use in my documentary as archived footage is external intelligence on the subject in hand which I would integrate in my documentary.
