Jason Voorhees, the infamous slasher from the Friday the 13th franchise, is best known for wearing a hockey mask to hide his deformed face. However, he didnt wear the mask until later in the series. In Friday the 13th Part 2, Jason covered his face with a bag most of the time during the killings, and in the first part of Friday the 13th Part III, he later got the mask he is most known for. When prankster Shelly goes back to the barn after pulling a joke on Vera and she tells him off, he’s attacked by Jason (off-screen), who steals his hockey mask and speargun - and that’s how he got the mask in the original timeline. Behind the scenes, the mask came to be thanks to 3D effects supervisor Martin Jay Sadoff, who was a hockey fan and had some hockey gear with him on set. He pulled out a Detroit Red Wings hockey mask for a lighting test, which director Steve Miner loved. The mask was later revamped and molded for Richard Brooker, who played Jason in Part III. In the 2009 Friday the 13th reboot, Jason takes a hockey mask from the attic to cover his face and continues with his killing spree.
