If you haven't seen the Star Trek, look away, because here's a spoiler: William Shatner is not in it. While Leonard Nimoy was given the privilege of donning his prosthetic ears one last time, Shatner was conspicuously absent from the film's symbolic passing of the tricorder. But, as writers Alex Kurtzman and Roberto Orci explained in an interview with io9, that wasn't always the case. In one draft of the script, there was apparently a Bill Shatner "Happy Birthday, I'm almost certainly dead" scene:
Orci: We wrote [a Shatner scene], it was in the script. Kurtzman: The very last scene when Spock and Spock meet each other, finally. And elder Spock is convincing young Spock that he couldn't interfere, because it would have diverted [Kirk and Spock] away from their friendship. And that their friendship is the key to the whole sort of shebang. Orci: He gave him a recorded message from Kirk. Kurtzman: He [elder Spock] said, "Don't take my word for it." And he handed him [younger Spock] a little holographic device and it projected Shatner. It was basically a Happy Birthday wish knowing that Spock was going to go off to Romulus, and Kirk would probably be dead by the time...
That would have been something, but I'm personally glad they ended the film the way they did:
Did you not stick around for this after the credits?
