[Quick Summary: While the rebels disable the Death Star's shield on Endor, Luke faces Darth Vader.]
I'm a big Ewoks fan. (I can't believe some people are not.)
How would I have introduced such a new creature to a franchise?
I would've probably dived in with the physical description, i.e., "short, bear-like, cuddly."
However, the writers had a more effective way to draw the reader in.
They began with character actions, then physical attributes:
"EXT. FOREST CLEARING - LEIA'S CRASH SITE
A strange little furry face with huge black eyes comes slowly into view. The creature is an EWOK, by the name of WICKET. He seems somewhat puzzled, and prods Leia with a spear. The princess groans; this frightens the stubby ball of fuzz and he prods her again. Leia sits up and stares at the three-foot-high Ewok."
Here's my short break down:
1 - Black eyes enter the screen [Not too much detail]
2 - He's puzzled [Now we're curious at his curiosity]
3 - He pokes Leia [Action and movement]
4 - He's frightened, but pokes again [We see his brave action]
5 - She wakes and sees a 3 ft. teddy bear [Finally the whole picture]
I liked that we didn't know the Ewok was 3 ft. until the end.
It's a surprise, and adds respect that such a short fellow would attempt the previous behavior.
WHAT I'VE LEARNED: If possible, describe a character with behavior first.
