I saw the trailer for this a few days ago and was confused. Isn't the Silver Surfer supposed to be a good guy, or did i miss something?
Kind of...
The Silver Surfer was the herald of Galactus, the devourer of worlds. Galactus is considered one of the essential forces of nature, and part of the balance of the cosmos.
Galactus requires unfathomable energies obtainable only from certain types of planets in order to sustain his life. The suitable type of planet need not be one where life is present, but it must have the potential to support life. Galactus usually employs a herald to scout the universe for those suitable types of planets. When the suitable planet is found, Galactus will usually land on the planet's surface and assemble his Elemental Converter, a colossal machine capable of draining all life energy from the planet within minutes. Galactus has been known to devour planets without the aid of his Elemental Converter on occasion, but the device makes the process more efficient. Galactus, seeing himself as a higher being, usually will not avoid a suitable planet simply because it is home to sentient life. Thus, over billions of years he has become one of the most feared beings in the universe, his vast power allowing him to lay waste to innumerable extra-terrestrial civilizations in his quest for sustenance. Nevertheless, he is not an evil being, but rather a force of nature whose feedings are necessary for survival.
Galactus has appointed a number of entities as his heralds, imbuing them with a minuscule portion of his Power Cosmic and sending them to search for edible worlds. Most of his heralds have either rebelled against him, betrayed him or been cast aside for some reason.
The Silver Surfer was a herald of Galactus, and it was Galactus who created him. The job of his heralds is to seek out suitable planets and announce his coming. The Silver Surfer rebelled.
A herald of Galactus is the absolute last being any civilization ever wants to encounter. It means that Galactus is coming, and the end of days draws nigh. I don't know if this movie is set after the Silver Surfer has already rebelled, or when he is still a herald for the devourer of worlds.
