While the Ewoks are taking care
of the stormtroopers on Endor, Han discovers
that the generator’s back entrance code has been
changed. R2 wheels into action & tries to open
it, but when he’s shot he can only sizzle
& smoke. Han tries to hotwire it until
he’s cornered by an AT-ST. When he finds out that
Chewy’s inside, Han gets an idea: use the AT-
ST’s radio to call for backup. He
does. When the back door to the energy
field generator opens, Han sticks
a couple of charges to the ceiling &, slick
as grease,* runs back outside. He escapes
just before the two bombs detonate.
* Not really. He looks thoroughly uncomfortable as he runs. I mean, I know the guy knows how to book it; I’ve seen Indiana Jones in which Harrison Ford bounds like an antelope on the moon.
