J.J. Abrams' rebooted Star Trek movies made huge changes to Zachary Quinto's Spock. Abrams' Star Trek movies take place in the alternate reality Kelvin Timeline so they could introduce a new audience to the characters of Star Trek without being bound to the established canon of the Prime Timeline. Besides Zachary Quinto's Spock, Chris Pine's Captain James T. Kirk and Zoe Saldaña's Lt. Nyota Uhura were also notably different from the familiar versions in Star Trek: The Original Series, originated by Leonard Nimoy, William Shatner, and Nichelle Nichols, respectively.
