Analyse 2 Opening Scenes To Your Relavent Genre

Here is the opening ten minutes of Disturbia, i was looking at the opening scene in particular to see if it includes all the codes and conventions.

In this opening scene, it introduces the main character Kale and his father sharing some quality time together, fishing. You can see the location, a river with mountains behind. We are not told anythng about the narrative or the plot, we also can't tell what the genre or themes are. There is no details of cast and crew. The films title is shown. Even though we see the location there is no information as to where that is. There is also can't tell the mood or tone until later in the scene. There is no signature theme tune.

I can't find a clip for Sweeny Todd.
