Nick broomfield-Biggie and Tupac

• Voice of god used throughout
• Participatory- Broomfield has an influence on the story as he goes round asking questions.
• Both use background music to convey the mood
• Broomfield is a 'run and gun' style director, goes and meets with people he wants to talk to rather than calling them in.
• Stock footage such as news clips are used.
• still images 

Amy- Kapadia

• Performative documentary. 
• The director has no influence on the film
• People are called in for interviews. Taken place in a professional studio most of the time. 
• Stock footage from other T.V shows featuring other celebreties
• Much more editing used to cut scenes and also hide bits which the director doesn't want to show. Whereas Broomfield tends to leave shots running for much longer
