I believe that the "para-lawyer" was The Rainmaker - but I've got no clue about the midnight TV host.
Does the kiddo ever let you play his new game, max?
daf, I'm afraid that your hint was too subtle for me. Do you mean to say that neither the actor nor the films are obscure?
The only other female "savage warrior" I've thought of was Sigourney Weaver in the Alien series. (She wasn't very savage in the first one until the last 60 seconds or so.) And she protected children in one or more of them... But exercise addict? No clue. And was she ever pregnant in a film? Anybody remember?
