Note how the script just ends.  Apparently we had no real ending in mind when we started filming.  The actual ending was partially scribbled on the script and partially ad libbed.  Surprisingly, it's one of our best endings.  It's not really a surprise, though; everyone knew he wasn't guilty.

Also notice our abbreviation for the defendant is PACM.  It's short for [the] Pennsylvania Chainsaw Massacring [guy].
