Juno film opening.

This is the opening to the film Juno, I think this is a good opening because it suits the aimed audience of the film, which would be teenagers and young adults because the scenery is drawn rather than real, and art is a huge part of young culture for this generation. Also the music, although thought by some people to be quite old fashioned suits the atmosphere and is a song that would probably appeal to teenagers and young adults, especially since music is hugely popular wth those generations.
From this into we instantly see the type of scenes where the film will be set and the main focus is on the main character, Juno McGuff.
I think that if the opening didn't have the scene beforehand, and just went straight into the opening titles then it would not attract as many viewers, as they could possibly get bored since it is just the character walking.

The technical codes of the opening are the lighting, which is quite bright and generally 'happy' which gives off the impression that the film is going to be a positive one that people will enjoy. It is mainly medium shots to get in part of the main character, Juno (who we know will be the main character now, thanks to the opening) and the background.
Symbolic codes are that the colours are bright and friendly, again giving off the impression that the film is going to be a generally happy one and that the main character is perahaps quite easy going. Clothing on the main character is very casual, showing this is not a formal film and appeals to the aimed audience. Body language is very relaxed, yet again showing the easy going nature of the character and how the film is going to be a happy, positive one rather than giving the impression it is going to be a horror or an action film.
