Hanna:
In this opening scene, the camera starts by panning through the trees in a snowy forest using a medium long shot to show the probable size of the landscape. Notice, the camera does not show the entirety of Hanna's face, only partially, hidden by a scarf and the surrounding trees. This is so not to give away the main characteristics of the lead role and keep her identity hidden.The intense, slow music played right from the start indicates that this is already going to be an action film. When Hanna disappears from behind the tree it also hints at a film containing mystery. The pace is sped up as Hanna shoots the deer and runs through the forest to retrieve her arrow, before she uses an eery declarative sentence of "I just missed your heart." -to end the opening and cut to film credits.
Back to the Future:
In this film opening, showing the boy's face is avoided and instead the camera is set up from low angles, shooting medium long shots of other things for the audience to focus on. The 'ticking' from all the various clocks in his home that the camera pans over, creates the build up before we see the boy arrive. We only ever see his lower legs and feet in this section. We see the boy using the amp system with extreme close ups of his hands turning up all the dials, this also adds to the big build up before he is blasted to the other side of the room by the noise. Already giving the impression that this is a comedic film.
Into the Wild:
In this opening scene, Chris Mccandless is filmed trudging through the snow, using a mixture of long and extreme long shots. The camera pans over the snowy grounds emphasising on the extent of the landscape. The soundtrack played over the opening scene is the song 'Long Nights' by Eddie Vedder, a slow and steady song with a steady beat, hinting at Chris' start to his journey. The camera uses lots of various shots of him out in the wilderness throughout this scene, a memorable one is a low angle shot of Chris looking up into the wide sky - a connotation of this being his love and admiration for the outdoors.
