Well, I can fill the time with what I think is an interesting question. In Superman (1978), I heard murmurs in Jor-El's dialog suggesting that Superman's powers derive from differences between the laws of physics in Krypton's galaxy and our own galaxy. From
a transcript:
COMPUTER
(JOR-EL'S VOICE)
Each of the six galaxies which you will pass through contain their own individual law...
(later)
...space and time. It is forbidden for you to interfere with human history...
At least this is how I interpret this dialog. I assume he means "law of nature", rather than "law of justice". Of course, the following dialog was much more overt, although I believe consistent with my interpretation above [ibid.]:
LARA
(pleading)
But why Earth, Jor-El? They're primitives, thousands of years behind us.
JOR-EL
He will need that advantage to survive. Their atmosphere will...will sustain him.
JOR-EL looks at his son, briefly smiles in pain and walks over to the area where the ship that will carry the BABY lies. There are information crystals placed in slots on the edges.
LARA
(walks after him, carrying the BABY)
He will defy their gravity.
JOR-EL
He will look like one of them.
LARA
He won't *be* one of them.
JOR-EL
No. His dense molecular structure will make him strong.
(looks at the rocket ship)
LARA
(looks down)
He'll be odd. (stares at JOR-EL again) Different.
JOR-EL
He'll be fast. Virtually invulnerable.
LARA
(staring at him)
Isolated. Alone.
JOR-EL
(sighs, looking down at the transparent crystal in his hands)
He will not be alone.
(holds up the crystal, and takes a long look at it)
He will never be alone.
Question: Will there be any explanation in the new film about how Superman gets his powers?
