Definitely Maybe Opening

Only analysing this clip until 4.32.

Definitely Maybe opening title instantly has the big institution brand come straight onto the scene, the theme music and iconic image of Universal Studios, shows the audience that this film has had a lot of money and expense go into it, and will appeal to the mass audience. After the main institution a smaller unknown company appears on the scene, by having two productions into the film makes the  film seem successful. Over the shot of the smaller company there are background noises of people talking in a work office place, even before the audience can't see where the characters are they know where the opening shot is going to begin.
Into the opening scene (0.39) we are introduced to the main character "Will" he is in an office building and is in a suit showing he is a middle class man, however the actions he does with throwing his pen on his desk shows his life isn't as simple as it seems, this is also shown by the beginning clip of the close up of an envelope, there is a loud and sad tone to the non-digetic music as the envelope hits the desk, this suggests this is what's troubling him. 
(0.48) When the character is opening the envelope a voice over of his voice is telling the audience what his situation is, we find out more about the character- he is getting divorced and how he is feeling. I think this is a good effective way of beginning a trailer as it gives the audience the characters perspective of what is happening in the scene directly to them, and getting them involved with scene and getting the audience to relate to the character. He is very saracastic which brings the element of comedy straight into the film. 
Again the comedy comes through (1.30) when he is beginning to set off from work to pick up his daughter. When the character says "it's a great feeling when you find the right track for the day"- (speaking is still in voice over) the audience is expecting the usual happy and jolly song but suddenly 'Bitch Face' by  Imran Hanif comes on which is quite funny, this is shown when the scene pauses to the surprise this song has came on- also by Will's face he didn't mean this song for his day song. 
When starting the song again 'Everyday People' by Sly Stone, this type of music is typically used in a romantic comedy as it is fun, youthful and happy fitting the genre of the film. 
The Camera Movement is tracking, following Will travelling through the city, we see through the mise en scene he lives in New York, with the stereotype of yellow taxis and seeing the Empire State Building behind him when walking. This setting is typically used in a romantic comedy so the audience knows they can rely on this film to be a film this genre is made to be like. 
The editing of the slides from each shot to shot is very effective, its creative as it brings the shots together even when they involve completely different places in each of the shot. It includes extreme close ups, close ups, mid shots, low angle, and high angle shots showing the main character and the mise en scene around him, showing the audience the surroundings the character is in and making them see what the character is seeing while he is walking, showing him in a normal day in New York. The shots are used in different sizes and moved from left to right to change the different shots using wipe edit, making the credits seem youthful and fun- the music helps continue this theme. The credit writing stands out against the black background, the writing is simple and in white which looks effective as the opening scene is busy with all the different moving shots and with the writing keeping still makes them appeal out to the audience. 
(3.45) When the music begins to fade out when he is entering the building the voice over comes on again, he is again talking directly to the audience making them feel involved and making them relate to what he is going through. When entering the building there is a huge crowd of children and parents gathered shouting and running around, this is where the audience and the main character find out their kids have had a sex ed class, this brings the comedy element in the film, this is a normal situation in life so the audience can understand how the scene is and relate to it.
