The death of her character in Freitag, der 13. Teil 4 - Das letzte Kapitel (1984) was filmed on a cold December
night. It was so cold out in the middle of the lake that Judie started
crying. Ted White, the stuntman who was playing killer Jason Voorhees,
became angry with director Joseph Zito for being so insensitive to her
discomfort and threatened to quit if Judie was not given a break from
being out in the cold water. She got hypothermia while filming that
scene.
