Speaking on Humans from Earth podcast Roberto Orci, said that the first two Star Trek films were about an origin story.
“It was about them coming together. So they weren’t the characters they were in the original series. They were growing into them and that continues on in the second movie.”
“So in this movie they are closer than they are to the original series characters that you have ever seen. They have set off on their five-year mission. So their adventure is going to be in deep space.”
