The immortals is based on the Greek Mythology story of Theseus. It has the basic idea of any Greek myth, an individual with great power and prowess in battle with a magical weapon given to him by the gods.
The trailer begins with the voice over from a disembodied voice. It establishes the basics of all the gods of Greek Mythology. The first scene begins with a large cliff wall with a small town carved into it, zooming out as the voice over explains what is happening. The main characters are established in the order of King Hyperion the Villain, Theseus the Hero, Zeus the King of the gods, and what appears to be a prophet who is also Theseus' love interest. Each character is appropriately voiced over, Hyperion having his goal of unleashing evil and Theseus being the only hope for both humanity and the gods. The epic story-line and its characters are introduced through voice over and in film dialogue.
The cinematography goes perfectly with what is being established. Many of the shots tend to have a golden color tint. The gods also have gold clothing which separates them from other non important characters. The shots help show the differences between the gods and titans through location. The gods are on top a mountain which over looks everything, in the bright sun. The titans are shown in a box deep inside a large hollowed out mountain. During a pre-battle scene, the entire landscape is shown, giving an idea of the shear size. During fight scenes the action focuses around the main characters, especially around Theseus.
The trailer is cut in a way that keeps some form of motion, shots last just long enough to be interesting before moving on. Action scenes go around characters talking, or pick up and drop depending on the music. The editing goes perfectly with the dialogue, sounds cut during certain quick sounds, or heavy music. There are many quick cuts as the action picks up and certain important plot points are stated.
The music is very well done, it doesn't interrupt other sounds, and it hypes you up to see the film. The beat of the trailer matches perfectly with the action sequences. It does not distract from the shots and scenes. It is appropriate and not overpowering.
The trailer is well made and delivers its plot and characters in a way that allows the audience to get an idea of the film, and want to go see it.
