To try and keep the tone up a little, I'd just like to add that it wasn't until Star Trek Into Darkness actually opened to the public that it was finally confirmed that Khan was indeed the villain, and Spock Prime had a cameo. The studio had maintained silence over both issues beforehand, with one cast member even flat-out denying the rumor that Cumberpatch was playing Khan. And lo and behold, we got both Khan and Spock Prime.
