Chris Pine has hinted that Kirk and Spock's relationship could play a key part in the new movie Star Trek Into Darkness.
Pine is set to reprise the role of James T. Kirk in the second Star Trek movie while Zachary Quinto is also back as Spock.
And Pine has suggested that the fact that these two characters are polar opposites could be a huge factor.
Speaking to MTV the actor said: "The definition of who these two people are definitely comes to bear in this film. It's central to what happens in the story.
"Spock is a logical man of cold reason who is run by laws, regulations and prescriptions. Kirk is a guttural, by-the-heart, instinctive and impulsive guy.
"Those two ways of looking at the world are central to these characters and their journey."
The movie will see J.J. Abrams back in the director's chair while Benedict Cumberbatch is one of the exciting additions to the franchise.
Star Trek Into Darkness is the first of two blockbuster projects for Pine in 2013 as he is also set to take on the title role in Jack Ryan at the end of the year.
Star Trek Into Darkness is released 17th May
