How are the conventions constructed differently in your two chosen films opening sequences?

Our two chosen films are Harry Potter and The Deathly Hallows part one and Monster inc opening sequences. The sound in both films depicts the genre of the sequence for example the Deathly Hallows features climatic music to emphasise the magical/fantasy atmosphere. Whereas the music is more child friendly and inviting in Monster inc. Another difference is the amount of editing used, for instance Deathly Hallows features lots of jump cuts and cross cutting with short shot duration to emphasise the action in the sequence.  Whereas Monster Inc is the opposite, with long shot duration giving the viewer lots of information through out.
