Unfortunately I wasn't able to get the video here as embed text was disables, but you can watch the opener here. It's the first two minutes of the video.

To start with the film productions logo is put up with non diagetic sound of sirens, so we already have an idea what the film will be about. This scene starts with an establishing shot of Sergeant Nicolas angel walking down a corridor, which looks like a very formal building. Of course as he's walking we don't know he's a sargeant, we discover this when hes right by the camera. So there's almost a sense of tension as the diagetic sound of his footsteps are the only thing to be heard.
Whilst this is happening more companies who were in associate with producing the film flash up at the bottom of the screen.
Then when Nicolas angel gets to the camera, there is an extreme closeup of his badge, and the non diagetic sound of a narrator comes in telling us about the sergeant, and his background. This voice continues through out the opening scene, and following each narration is a clip. Another non diagetic sound track cuts in under the narration as well to give of he feeling of the crime caper, as the music isnt exactly serious with big band instruments, playing small licks. And the mismatch between the action and the track gives of the comedic value of the opening.
As the scene continues on diagetic sound is added in, like the pen clicking for when he's done his exams, and this is to help the watcher get the feel of what he's doin or has achieved. A sound easy to relate to.
Through out the opener there are following pan shots and tracking shots of the sergeant as he makes his way through the police station, the diagetic and mise en scene give us a feel here of the surroundings, the mise en scene being the location in a big posh building with office props around, and of course people occupying them.
The shots of the action are very quickly edited and have fast transitions to give off the energetic feel and to get the audience to relate to the upbeat lifestyle of an officer, it has point of view shots from the sergeants prospective to show the audience, how upbeat the job is and fast paced.
It uses different length shots throughout also, switching quickly between distances, again to relate to the upbeat and fast pace atmosphere.

This opener gives us a feel of the upbeat life the officers have, but also the comical side, with the diagetic voice, and the sound track. Maybe a technique we could use if we were to make a crime caper.
