Novels rarely make good movies, mostly because they are simply too long and involved.
The good movies that come from novels are (almost always) films where the director has told a different story with the characters/setting of the novel. This is why we use the word "adaption" when talking about novel -> film.
Lord of the Rings is a classic example. It's (thank god) not the novels. Master and Commander is another excellent adaption, again, it's not any one of the 20 novels, but rather an independent story within that "universe". Blade Runner is another good adaption -- yet again the story being told is not the novel.
If there was a report saying an Asimov short story was being developed, I'd whoop for joy.
But color me skeptical that either of these will be anything other than I, Robot all over again.
