Hawk the Slayer/YMMV

"Filmmaker 1: We need a giant!
 * Cult Classic
 * Snark Bait
 * So Bad Its Good: A lot of people think that this is one of the best Sword and Sorcery films, if not the best before The Lord of the Rings got in on the action. It has silly string as a magic immobilization spell.
 * Special Effects Failure - Where else can we find a movie with silly string and bouncy balls as magic spells? your mileage may vary
 * Extends to the casting:

Filmmaker 2: My friend Bob is kind of tall...

Filmmaker 1: We need a dwarf!

Filmmaker 2: My friend Steve is kind of short...

Filmmaker 1: We need an elf!

Filmmaker 2: My friend Jeff is kind of skinny and can talk funny..."
