Thandie Newton: Embracing otherness, embracing myself

MW once said something to me about good actors not having a strong identity. (This was based primarily on observations of homosexual actors.) Is this another illustration of his claim? Is there a link between the lack of identity and narcissism as well, or are these two separate traits? I don't have time to watch the video at the moment, but it seems to be immersed in pop psych and therapeutic language and contemporary liberal values.
