Species (1995)

My memory of this movie has been corrupted by my memory of Mimic (which I think has to do with giant subway cockroaches that turn into Mira Sorvino?). In Species a beautiful blonde woman is actually an alien—or bioengineered, or a bioengineered alien—and she keeps having sex with men and then killing them in unusual ways. I think she's being tracked by Anthony Hopkins or something, and she may be trying to reproduce. Does something come out of her mouth like in Alien? Is there any nudity?* These are important questions.

Not Anthony Hopkins.

* Google says—and I am paraphrasing, here—"Oh, yes."
