Watch the Title: This is Tomorrow

This is Tomorrow

• The first shot slowly fades in from black, to show an black, silhouette image of a spire-topped building ahead of a silhouette of a cityscape in blue. Blue has connotations of sadness, and the black building's tone is imposing and dominant.
• Black planes of different transparencies fly over the city, white vapor trails following them. These vapor trails cut through the blue sky, leaving white streaks across it. The varying transparencies of the planes could be there to show how close the plane is to the viewer.
• It then starts to rain. The falling rain is a good indicator of what is soon to happen (dropping bombs), and is also a symbol of sadness.
• The shot changes to show three planes from below, with two white vapor trails following them. The planes are moving down the frame, which shares the symbolism of the rain.
• An image of a pressure clock is shown. The hand of it moves up and down at irregular intervals. This could symbolize the fluctuating emotions of the those who will suffer from the downpour of explosives.
• The planes are shown from the bottom again, but this time closer up. It is now clear that these planes have German symbols on the undersides of their wings, indicating the situation (the Germans bombing London).
• A shot is then shown of the planes from above. This means we can see a vectorized map of London beneath them, with the signature River Thames in show (instantly recognizable by Eastenders viewers). This highlights the location of the opening.
• The next shot shows two planes at a close 3/4 angle, with several bombs falling from their undercarriages. The bombs are moving slowly, which builds up tension towards their imminent fates.
• As the two planes fly out of shot, more bombs drop from above the frame. A very close up bomb falls into view, obscuring the screen into black. This is used as a visual transition into the next shot, which is various obscured images of the planes and the city below. These images are highlighted by flashes of white around their edges, which symbolizes the explosions.
• At the end of this sequence of events, a short paragraph concerning the Queen's Hall's destruction in 1941 is shown. This explains what everything previous was about. This is an unusual feature that is very rarely used in film openings, but it is very useful for clarifying if the events portrayed in the film are real or not (even if they aren't - Troll Hunter, for example).
• The text slowly fades out to show a continuous pan of the battered, smoking cityscape. The buildings have black silhouettes, symbolizing mourning. The first credit appears over the top of the ruined buildings in a white, italic font. The names of the persons involved are in capitols, highlighting their importance.
• The pan continues, and another title is shown - only one name this time. The distance of time between each title is long, so as to embed the image of the ruined city into the viewer's mind, and also to emphasize that sad mood.
•  The pan continues to show a white crane using a wrecking ball on the buildings. Then, dark blue silhouettes of bulldozers move in from the left to obscure the view - another visible transition.
• Another paragraph is shown. This one discusses the London County Council's plans in 1949 to construct the Royal Festival Hall. Through film grammar, this suggests that the wrecking ball and bulldozers of previous were clearing away the scenery for this construction.
• The dark background then fades to a lighter shade, and a line-drawing of what appears to be a dish-shaped roof is seen moving down the scene, with another line moving upwards with a hook on the end. This implies that the wrecking ball crane of previous is helping with the construction of a new building. There is also a credit name shown in this shot. 
• The shot continues, to show more ropes bringing more pieces of building downwards. This continues the theme falling (rain, bombs) that is seen throughout the opening. Two more credit names are shown.
• Now, a short paragraph about the opening of the Festival of Britain's opening in 1951 is shown on a much lighter background that previous paragraphs, implying that the situation is getting better.
• A waving red triangle comes into view - it is the first thing that is in a colour other than blue, white or black in the opening. This indicates a colour theme; Red, white and blue - the Union Jack. This triangle, as the zoom-out progresses, is revealed to be one of many flags on a line of bunting - a party?
• Various blue, white and red streaks move across the shot, as another title is shown. They stop to form an aperture-like pattern around another credit name.
• Three lines move from theft to the right of the screen, with coloured circles appearing upon them - this could indicate notes on Guitar strings.
• This scene then fades to reveal two suns, each in opposing corners, rotating slowly. The sun is warm, a source of light - this is a happy symbol, conveying the mood of the piece as is currently apparent. A credit name is also shown between the two suns.
• 5 cubes fade into the scene one by one - is this the building that was being constructed before? A credit name is shown alongside these cubes.
• The opening then ends to reveal the building that was being constructed along with the title: THIS IS TOMORROW. This ends the build up of the opening, and relieves us of our wonderment of what was being built. A boat is seen moving in front of the building, which clarifies it's riverside location.
