Coming back from UC this movie carries on a lot of details. There is something really cryptic about this movie, lots of what characters says echoes with some other things in the film. Especially for the first two part. After things get action and only evident symbolism get out.
Excalibure at the theater, the word "rag(e)" behind little Bruce when his parents get shot.
On the coats of arms of the Wayne family we can see: a blade, a hand and a horse (i'm not sure but it fits all the other content).
Blade will surely be Wonder Woman. Hand i believe is Batman, he uses his hand for access to the suits, wich will parallels Lex access to the ship and the "shadows", the cave. The horse is Superman.
When Clark first meet Bruce they are horses in the background of his shot and a black car (?) for Bruce. Two ways of locomotion' Superman is a force of nature, a "god", when Bruce has not such power, natural power, he gets most of his superpower from technology.
The horse are also symbols of travel to the land of the day. At the begginin Bruce passes one in the smoke after his building chrashed. There is a journey to, through, death in the movie. Bruce will get to save his "Martha".
The horse are also linked with the force of the authority. Police rides them multiple time. In the office of the governor (the woman always in white) they are horse figure. They are also one when she goes to Lex house at her left on the desk, and to image the doom he prepared, Lex makes sound of horse ridding with his finger.
This authority-horse also link Superman into Bruce dreams. Most of Bruces dreams are repetition of Superman action, he brings flower to his mother when Clark brings flowers to Lois (when Clark call her mom they are flowers painting up her bed, also a flower paint at the end when she see Lois before the funeral, and give her a package). At the beggining Bruce his lifted from the ground alike Superman, something of a christ figure, flotting towards the light.
We get to the third dream, both repetition of Superman action in the desert and a premonition of what is to come. They are Superman policemens (so the association horse-authority) wich is represented in Bruce mind since the police is against him. Bruce has to deal with the pain of people loosing theur lives, he live in the skin of Superman sins, but he was manipulated. Where Clark look to reveal things about with "real" news. So Bruce can represent the consciouscness of Clark (the dark, the shadow dealing with problems of guilt) where Clark is the light trying to reveal it. Spreading light on the hidden.
Bruce will cary his cross in his cave when Clark will go on top of the moutain above the mist of the clouds (Pa Kent died letting go in the mist of a tornado).
There is a lot of talk in the movie about police not doing the right thing and newspaper neither. So we get to Lois. Whom obtain a red book with a bullet. Both are Lex, at his party he is presented as a lover of books, livrary, etc. He talk about his father and books. He also talks of knowledge and power. He is a man without power innate (alike Bruce) but he has knowledge and technology. Bullets.
The connection beetwen Bruce and the hand is also made when Clark ask a woman outside the police office. She says only a hand (or fist?) can stop him. That is the only things he understand.
The connection with Wonder Woman and the blade his also made when they get to Arthur's swords, a fake.
Mutliple time in the movie the image of the Warrior comes by. They will be three as one. There is a nice interconnection of the authority-knowledge-nature-god-moral-discussion/democraty through the films since Clark works at a newspaper and technology often convey the information.
There is much more interesting information through languages speech wich i don't always recall but that links some scene to others. I would need to rewatch it to catch more details and give more accurate understanding of the films.
There was innocence multiple time recurring too. With Lois and other tiles. The movie get on taking our responsability, grow. Superman will die, in parallel he was already touched by the dead in Mexico, and will be revorn to complete his lessianic figure journey.
