Originally this was going to be much shorter and titled "Predator backpack and animatronic cannon" as that is what the majority of this instructable is about, but that would be a disservice. This is really a story of how a few members of a Predator fan group, known as The Hunter's Lair, came together to create what we hoped would be the best replica Predator costume ever made- an accurate replica of the costume Kevin Peter Hall wore in the first Predator film. This was an enormous collaborative effort, and while this instructable will focus primarily on the creation of the backpack and cannon it wouldn't be right to not tell the whole story and give credit to all of the extremely talented individuals involved in the creation of this costume of this wonderful film creature.
A seed is planted...
At the Monsterpalooza 2012 convention there was a panel that was devoted to the 25th anniversary of the first Predator film and many of the original artists from Stan Winston Studios that worked on the film were there to talk about the making of the film. Several members of The Hunter's Lair attended as did one very special individual- Jamie Hall.
After speaking with Jamie, two of the Lair members by the names of Gene Emory and Damon Silva had the idea of meeting up at Monsterpalooza the following year and creating a replica suit for Jamie to wear. The goal would be to make a replica of the Predator suit Jamie's uncle wore and have Jamie wear it around the convention hall. Matt Winston of Stan Winston School of Character Arts later had the idea that it would be really cool if several members of the original film crew could again return and then suit up Jamie just as they had with his Uncle Kevin 25 years ago. Jamie was thrilled with the idea and what would be known as the "Jamie Hall Predator Suit Homage Project" was born.
But first we need to back up a few years...
