The other day I watched a great old movie called The Big Lie.  The story is basically that two women, Bette Davis and Mary Astor, are in love with one man.  He is in the army and goes to war somewhere and presumably dies.  Well, Mary Astor is pregnant by this guy and as a concert pianist, is very inconvenienced.  Bette Davis tells her she'll do anything if Mary Astor has the baby in secret, then gives it to Bette, and no one will be the wiser.  Mary Astor does this, all the while smoking like a chimney and carrying on like a very temperamental artiste, and it's pretty fun to watch.  (I watch long movies in spurts so if I leave stuff out, sorry.)  Anyway, the love interest is not dead, comes home to Bette and his child, and whaddyaknow Mary Astor threatens to tell him that SHE, Mary Astor, is the mother of the child so Bette Davis beats her to it.   The father of the baby says to Mary Astor, well you're the mother, you're entitled to take the baby.  Then he says to Bette, "At least we have each other."    Whereupon Mary Astor informs Bette that she'd like a drink, won't be staying for lunch, and that she can keep the damn baby.  Then she starts pounding away at the piano.  Happy Mother's Day.  I would say that Mary Astor is a very underrated actress.
