The thing that comes to mind for me (for some reason) is the original Day the Earth Stood Still. Patricia Neal has some lovely moments as I recall. (It has been a while since I watched it, I could be remembering what I want, rather than what is there.)

Uhura in most of the Star Trek movies, but one of my favorite moments is her dealing with the guy who assumes she is feek and weeble, in Search for Spock? I've forgotten which movie it is in.

Rebecca and Amanda in Highlander.
