Nichelle Nichols: In "Plato's Stepchildren," Uhura and Kirk were supposed to kiss under duress from their captors. It became an issue with the director and Gene Roddenberry finally decided to shoot the scene with and without the kiss. Bill Shatner kept kissing until there was only time for one more take. When the camera zoomed in, Bill crossed his eyes and the director didn't notice it until the next day in dailies. Of course the last scene was unusable and they had to go with the kiss scene, which became history as the first interracial kiss on TV.
