Although it has never actually been identified in the films, "Billy" is the name by which it is referred to by writers, directors and members of the cast and crew on documentaries and interviews. The name was given to it by its real-life creator James Wan, who is the director and co-writer of Saw. There is disagreement that the name is spelled "Billie", although Wan himself spells it "Billy".
The endurance and popularity of the Saw franchise has resulted in the production of Billy merchandise, as well as references in other media. Billy has become a type of mascot for the Saw franchise.
Billy appears to be a male ventriloquist's dummy, as its jaw is movable in order to give the suggestion that it is talking; however, it is not used in the same manner, as the entire doll is frequently seen moving on its own. Its face is white, with a protruding brow and cheeks that have red spirals painted on them. His red lips form a grin. His eyes are black with red irises, and his head is topped with black, messy hair.
Billy is always depicted wearing a black tuxedo, with a white shirt and gloves, red bow tie, and red handkerchief in the pocket. He also has red Mary-Janes for shoes. In the short film, he is seen wearing a green bowler hat. He is often riding an old-fashioned red tricycle. The only sound originating directly from him is a generic electronic cackle much like one would find in a Halloween-type toy.
It was revealed in Saw IV that Billy's design was taken from a smaller, slightly different version that John had shown to his then-wife, Jill Tuck.
According to Wan, the construction of the original puppet's face for Saw involved clay, papier-mâché, and black ping-pong balls with the irises painted in for the eyes. He's also said to have paper towel rolls somewhere inside of him. To make him move, the puppeteers pulled him along on a fishing line.
For Saw II, Billy was redesigned with mechanical features that could be manipulated by a remote control, including his unhinged jaw and his eyes.
For Saw III, the prop crew was given the original puppet, but found it unfit to work, as time had damaged it. Instead, they recreated Billy, using waterjet-cut foam for his body instead of fiberglass, equipped with plates to hold the puppet together and magnets to attach him to his tricycle. The back of his head was removable, to make it easier to slide the animatronic pieces in.
For Saw IV, the prop crew again made the body of waterjet-cut foam, held together by metal rods. They used strong magnets to make a flat rear for the puppet, so it could be easily positioned on any metal surface. The resin-filled ping-pong ball eyes were moved with a remote control, as was the mouth.
In the Saw films
Saw (short film)
Billy appears on a television screen and tells David about the reverse beartrap that he is wearing. After David escapes the trap, Billy rides in on his tricycle and congratulates David on his success and tells him that he is free to go.
Saw (feature film)
Billy is first seen on a television set by Amanda Young, telling her about the reverse bear trap that was hooked into her jaws. Once Jigsaw explains where she must find the key to unlock the trap, Billy is seen again, congratulating Amanda on her success, wheeling into the room on his tricycle to deliver the message of her freedom.
Later, Adam remembers seeing the puppet in his apartment when the lights went out. While searching through the dark rooms using his camera flash, the puppet's eerie laugh rings through the apartment, and Adam hits it with his bat until it stops.
When detectives Tapp and Sing uncover Jigsaw's latest hideout, they snoop around his desk, pulling off many blankets to reveal the different contraptions of the mastermind. The two detectives are shocked when they find Billy staring back at them from under one of the blankets.
Billy is seen on the screen at the beginning of the film, giving Michael hints about the death mask he is wearing. It plays out similarly to Amanda's test, except Michael dies.
Later, when the detectives discover Jigsaw's new hideout, several officers walk up a caged staircase, and are greeted by Billy, who wheels into sight at the top of the stairs on his tricycle and laughs. The cage then becomes electrified after one officer steps on a rigged stair that breaks his legs.
Jigsaw can be seen constructing Billy in a flashback for the purpose of Amanda's game, painting the puppet's face. Later, Billy is used to inform both Troy and Kerry of their respective traps. The puppet is also seen in the background of a flashback that features Jigsaw and Amanda discussing her loyalty.
He is also used to remind Jeff Denlon of his dead son at one point, by being laid down next to his bike in the same position as Jeff's son when he was killed. He then lets off a mocking laugh.
After Jeff cuts Jigsaw's throat, a reflection of Billy can be seen on Jigsaw's heart rate monitor for a split second.
Billy is first seen when Rigg awakes after being attacked in his apartment and rendered unconscious. Rigg opens his bathroom door, pulling a trigger-wire from a TV set. Billy appears on the screen to explain Rigg's game. Upon leaving the room, Rigg is greeted by another message concerning his first test, referring to a woman Jigsaw deemed to be a criminal that had been placed in a machine that would scalp her.
Agents Strahm and Perez later find Billy in a room in a school, sitting on a chair surrounded by candles. From a microcassette recorder hung around the puppet's neck, Perez learns that her partner will soon take the life of an innocent man (who is later revealed to be Jeff) and that her next move is critical. Billy's eyes begin turning to Perez while a low voice on the tape murmurs, "Open the door." Perez leans in to hear this last, at which point Billy's face explodes, blowing shrapnel into her face and neck. Perez collapses into Strahm's arms as Billy begins to laugh.
There is also a flashback of Jigsaw giving an early version of Billy to Jill as a gift, looking less menacing than the most recent version. An interview with Tobin Bell revealed that this was the beginning of a storyline concerning the origins of Billy, as well as his tricycle, to be explored in future Saw films.
Billy appeared in the opening sequence of Saw V, to tell Seth of his game. This game is later revealed to have been set up by Hoffman to frame Jigsaw and kill Seth. It is unknown how Hoffman knew that Jigsaw had the same puppet. According to a list of potential Jigsaw victims, Seth was the second person tested after Cecil, Jigsaw's first victim. In that test, Jigsaw didn't use a puppet.
However, Cecil's last name on the list is Fletcher whereas in Saw IV his last name is shown to be Adams. It is possible that Jigsaw could have tested two Cecils, and the police didn't find out about Adams until Jill told Strahm about him. If there are two Cecils, then Jigsaw may have used a puppet for Cecil Fletcher's trap and the police found out about it.
Billy is also seen at the beginning of all of the team's traps.
The early version of Billy from a Saw IV flashback is seen in the background of a flashback explaining the connection between Jigsaw and Hoffman.
Billy appears on tape in the opening trap, which pits Simone and Eddie against each other. He also addresses William Easton during two of his four tests (Jigsaw himself addresses William via video in his first test). He appears "in person" in William's second test by way of hanging from a noose, and on video in the fourth. Saw VI marks the first time Billy was purposefully shown in person to deliver test information to victims. Snippets of the Seth Baxter tape which Billy is featured in are also played.
Billy appears for the final time in the final Saw film, Saw 3D. He gives Ryan and Brad instructions to their trap in person, along with multiple appearances throughout Bobby Dagen's game. And his final appearance was in Hoffman's secret hideout at the end of the film, Hoffman blows it up, and Billy is destroyed in the explosion.
In other films by Wan and Whannell
Leigh Whannell stated at the world premiere of Dead Silence that he was going to put Billy in every movie he made from now on, but its presence might not be obvious.
In the 2007 film Dead Silence (which is made by James Wan and Leigh Whannell, the creators of the Saw films), one of the puppets, who appears on the film's poster and wears the same outfit as Jigsaw's puppet, is named Billy. The Saw puppet is also seen in the movie for a brief second, in a shot that reveals all of Mary Shaw's puppets in the attic above the theater.
A graffiti-style painting of Billy's face can be seen on a wall in James Wan's film Death Sentence.
Billy can be seen in the corners of two panels near the beginning of the comic, foreshadowing John's eventual transformation into Jigsaw. The comic also appears to mark Billy as one of John's creations at the toy factory where he worked, but this backstory was negated by Saw IV.
Saw: The Video Game
Billy appears throughout the game delivering hints and objectives to the player. He was also featured prominently in marketing for the game.
Saw II: Flesh & Blood
Billy appears in the sequel to Saw: The Video Game once again voiced by Tobin Bell. He has the same role as in the first game, giving hints and clues to the player. The player can also collect small Billy dolls throughout the game. These dolls require the player to solve more complicated puzzles in order to obtain them, but they are off of the main path, so the player does not have to get them. Flesh & Blood is also the only time in the Saw franchise that he is actually called "Billy."
Theme park attractions
Billy appears on numerous screens throughout the queue line of SAW: The Ride at Thorpe Park, England telling riders that they are not worthy of the life they have been given. He also appears on his tricycle at the start of the ride itself, telling riders what they will experience, before the car travels up the lift hill, appearing on a screen and saying 'GAME OVER' and finally at the end of the ride, where his head can be seen on a shelf covered with body parts.
The Saw Alive maze, also in Thorpe Park, allows parkgoers to be photographed with Billy.
Billy appears several times in the haunted house, Saw: Game Over, at Universal Orlando Resort's Halloween Horror Nights, specifically from its 2009 event and nineteenth year, Halloween Horror Nights: Ripped from the Silver Screen.
In popular culture
A line of replica Billy dolls has been released for consumer purchase, mainly through offbeat gift stores. It retains the main characteristics of the doll, though is much cleaner in appearance. Halloween masks and costumes have also been released for purchase.
In the Koi Pond episode of The Office, Dwight Schrute dressed up as Billy for Halloween.
