As the creative and technical consultant on Friday the 13th Part 3 and
Friday the 13th The Final Chapter, he is the main reason why the film's
psychopathic killer Jason Voorhees became so famous for wearing a
hockey mask. While also playing the role of a State Trooper on Friday
the 13th Part 3, Ballard brought an old 1950s hockey mask to the set to
joke around with the other cast members and director Steve Miner and
the writers thought a hockey mask would go great into the script and to
have Jason wear it. When Ballard returned to work on Friday the 13th
The Final Chapter, the filmmakers decided to keep the hockey mask with
Jason Voorhees and it has been used in every Friday the 13th film since
then.
