By “ordinary looking,” I presume you mean, “human” as opposed to the bizarre fin-nosed space aliens that get most of the attention in Hollywood? $10 million and a plastic surgeon and anyone can look like that. Not anyone can be made to look like Jennifer Lawrence, although she is drifting towards the space alien look lately. The body snatchers have come for her.
I mean, plain Jane never look at her twice in public.
The magic of Hollyweird makeup transformation. She is not ugly with out stage makeup, just exceedingly ordinary.
My wife says she is a good actress, I would not know.
