Adaptation: be true to the spirit of the source

The Writers' Guild of America (West) has an interesting article up on its website about adaptations, talking with screenwriters who have adapted various source materials for film - incuding novelists who have seen their original work adapted by others and had a hand in adapting their own work themselves. Apparently about sixty per cent of all feature films of adaptations, and it's been a subject much debated on my MA screenwriting course this trimester. Anyway, the article's well worth a look, if such things interest you... [Thanks to the WGGB blog for the link, by the way.]
