'Trek' (TOS) experts: id actress?

I think the Black actress in this snippet looks a lot like Nichelle Nichols. Any opinions?

It does look like her, what movie was that from?

“Three on a Couch” (1966) (and, no, she’s not credited).

It doesn’t look like her to me, more than superficially. I think the actress in the clip has a much more pronounced nose.

Looks like her in the beginning but the similarity lessens as she gets closer to the camera.

Cool! Thanks for the input.

I don’t think that’s Nichelle Nichols. That doesn’t even look much like a woman; more like Kenan Thompson in drag.
