The whole nature of the original film also reflected that more liberating sensibility with how creatures like Jawas and later the Ewoks affect things without initially intending to, just be their unplanned encounters with the heroes.

Incidentally since I'm a shameless attention whore, I'm currently working on the first treatment (hopefully to become the first of three scripts) of a completely redone version of the prequels which pretty much removes the reliance on fate or prophecy as story elements and back to a more fanciful take ala the originals. The progress of that and other story points can be found in the Script Writing and Re-writing section of the forum. Give it a look if interested.
