If Roberto Orci has his way, then fans will see both Leonard Nimoy and William Shatner in the next Star Trek movie.
While Nimoy has been in the other two movies, Shatner has not taken part in the Abrams rebooted Star Trek movies.
According to Badass Digest, “I have learned that the script for Star Trek 3 includes a scene that reteams Shatner and Nimoy onscreen as Kirk and Spock for the first time in canon since 1991’s Star Trek VI: The Undiscovered Country. It would be a pretty huge moment for fans of the franchise, and likely the last time we’ll ever see Shatner as James T. Kirk in official continuity.”
Will the actors sign on for this, or will it go the way of the cameo written for Shatner in Star Trek (2009)?
Time will tell. Until then, treat this as a rumor.
