Is it strange

I knew the name Julia Ormond as soon as I read it in the credits of Surveillance, but when checking Imdb to see what else I've seen her in, I looked up and down the list of her acting credits and I have seen nothing else she has been in. Just Surveillance. That's it.

Why do I know her name if this is the case? When I saw she is British I thought, "Ah, I bet I have seen her in a TV series or something." But no, there is nothing there.
