13 Things You Didn't Know About Friday 13th Part III

The original film had set Jason Voorhees up as being physically deformed from childhood, although the reason for his disfigurement was never mentioned. That random decision painted Steve Miner into a corner for Part 2, as those kind of prosthetics would need to be constantly reapplied, taking hours a day and costing more than his meagre budget would allow.

He solved the problem with the infamous 'pillowcase mask', an image borrowed from 1976's slasher The Town That Dreaded Sundown. Miner decided to jettison the sack for Part 3 (owing to its similarity to the makeshift hood worn by the protagonist of 1980's The Elephant Man), but the original problem remained, compounded by the fact that the shoot would be three times longer than usual because of the time-consuming 3D lighting and staging process. They needed a new mask.

The film's 3D supervisor Martin Jay Sadoff was a huge hockey fan. During a lighting check, Sadoff passed Brooker a Detroit Redwings goalie mask from his bag to avoid having to make the actor up. Miner took one look and fell in love with it.

When tests showed that the mask was too small to use in front of the cameras, makeup effects director Doug White created a new larger VacuForm version. Art director Terry Ballard added three red triangles around the eyeholes to give us the iconic mask we know today, Brooker wearing a faceless 'flesh hood' behind the mask to give the appearance of Jason's misshapen head without having to wear the full-face prosthetic.
