Snatch:
Narrative function: Montage sequence that introduces each character.
Conventions displayed: Bold font, conveying the characters; there is also a continuity with the font, yet not with the coloured background. Title displayed fairly quickly, upon a diamond; which the audience know has been stolen, suggests genre.
Characters introduced: All main protagonists are introduced and the type of character they are; also their character name.
Cinematography: Colours used suggests genre as they are fairly basic, yet bold.
Camera/editing: Camera tracks the diamond as it is passed around, then the money, etc... . Ends back with the diamond in the mans hand; where it started. Editing is tight and cuts between each character smoothly.
Reservoir dogs:
Narrative function: Starts off with a narrative by a very monotone man; matches atmosphere. The narrative though quickly turns into a music, which narrates until the end.
Conventions displayed: Yellow font which is used throughout; so this is good continuity. Title introduced after the actors have been introduced. Title rises from the bottom of the screen and is placed at the top, above the characters.
Characters introduced: A large group of men in suits; represents power or authority.
Cinematography: Colours are bright, in contrast to the atmosphere.
Camera/editing: Camera tracks the men in slow motion down the road. Cuts from them leaving the bar; which is dark, to a dark screen to the characters outside in the bright sunshine; contrasts earlier scenes.
Godfather:
Narrative function: No dialogue just music; which is easily recognisable to the the film genre.
Conventions displayed: Gun shots and blood appears on screen in every scene; conveys the genre. Images of objects associated with Italian-American gangsters. Red used to signify death and evil; portrays genre.
Characters introduced: The three main protagonists (The Godfather, Al Pacino's character and Diane Keaton's character). No names for the characters, just the actors/actresses names.
Cinematography: Colours of red suggests death and evilness; conveys genre. Black and white background stands out; could suggest good vs evil.
Camera/editing: Smooth editing between each shot, gun shot and blood on screen depicts genre.
