Theme: Up

Growing up.
Antonio measures the height of his boys on the wall. The older brother, Vincent is shorter than his younger brother Anton. Vincent is not measuring up.

Vincent receives a leg surgery to increase his height, so that he is standing taller than before. This is symbolic representation of Vincent’s beginning of achieving higher self.

Looking up
There are numerous rocket launches in the film. His goal to go “up” is shown every time he looks up; he’s “the only one who watches every one of them[the launches].”
After a while, Irene also looks up.
“I see that I’m not the only one who looks up every time there’s a launch.” - Jerome.

When Vincent has to rescue his brother from drowning the second time, Vincent looks up the sky and sees the stars as the clouds clears. (See concealing/revealing)

Going Up
All spacecraft launches goes up into the sky. And finally, Jerome actually goes up in the space at the end, and looks down at the Earth.
“I’m going up.” - Jerome

Higher self
Vincent becomes Jerome, and he is able to inspire others and made them open their eyes to possibilities. He achieves his dream of going to space and although Vincent dies, Jerome lives on in a form greater than us, something that lives in heart of others.
