Sea of Love (1989) starring Al Pacino and Ellen Barkin? Al plays a detective who goes undercover answering dating ads to catch a woman killing men, which is when he meets the incredibly sexy Ellin Barkin. I love this movie, but hardly anyone I have ever known has seen it.
Oh yeah, it also stars John Goodman, who a friend of mine met once, and apparently he has a head of gigantic proportions. I was at a barbeque when he told me this, and to illustrate the immensity of Mr. Goodman's skull, he said, in his St. Louis accent that was somehow almost Canadian, "It was the size of that propane tank over 'der."
Anyway, the reason I'm writing this is not to tell about a portly actor's head but to say that that this film was the performance of a lifetime for Ellin Barkin because, as I said, she's sexy as all get out, but if you look really, really closely, she is not all that attractive. Yet, that doesn't at all stop her from being undeniably hot. So, without the benefit of natural good looks, like so many other leading ladies, she manages to exude nonstop sex appeal in every one of her scenes, and to be fair, her acting is quite good here too.
Can you think of any other actors or actresses who are hot despite not being all that good looking? I'll spot you Benicio Del Toro.
