Doors have been used so far in “The Godfather” to help the audience understand many different ideas.
Doors have been used to show separation: during the scene where Luca Brasi is getting ready to go out the camera is looking at him through a door. This makes the audience feel almost as if they are spying on Luca, and that what he is doing is something the audience should not know of or be a part of.
Doors have also been used to show a transition between the mafia and family life of the Corleones. During the wedding scene all mafia work is done indoors, while the party and family is all outdoors. This makes the separation of the double world many Corleones live in more evident to the audience.
As the movie continues doors may be used to symbolize multiple other ideas. A door may symbolize a tentative relationship between a Corleone and client, as a door can shut at any moment. This tentative relationship may also be seen between the characters in the movie and the audience. The camera is often outside of a door looking through at the characters, and the door may be shut on the audience having the effect of suspense. Doors may also be used to portray the idea of a way out for Corleones, clients, and the audience.
The motif of doors have been used very effectively throughout the film so far and I am looking forward to see how they will continually be used.
