I just saw the interview of Nichelle Nichols on 92Y for "Women Pioneers in Television." She of course spoke about her encounter with MLK. She really
stretched it out, compared to what I'd heard before. She also added that he called her on several occasions afterward to "check up" on her, making sure she was still sticking with it... Sounds like she IS embellishing her story over time, because I don't remember this from interviews I heard when she was much younger.
