Prosthetic makeup also known as special makeup effectsorFX prosthesis, is the process of using prosthetic sculpting, molding and casting techniques to create advanced cosmetic effects. Prosthetic makeup draws a straight lineage from the Stagecraft of theater and can be observed at the birth of science fiction cinema with Le Voyage dans La Lune, a 1902 French adventure short film directed by pioneer of special effects Georges Méliès.
The work of makeup artist Jack Pierce furthered pioneered early Hollywood prosthetic work and is best remembered for creating the iconic makeup worn by Boris KarloffinFrankenstein, his makeup for Lon Chaney Jr.inThe Wolfman.
Modern prosthetic makeup was revolutionized by Christopher Tucker whose work on The Elephant Man was considered so ground breaking that when it failed to win any recognition at the 53rd Academy Awards letters of protests argued for it to receive an honorary award – this was ignored but did lead to the creation of the Academy Award for Best Makeup the following year.
The process of creating a makeup prosthetic appliance typically begins with concept art, created by the artist or production. Once the actor has been chosen, the effects artist will prepare the actor for the process of taking a mold of the actor's face, head or body part. This process is called lifecasting. Lifecast molds are made from prosthetic alginate or more recently, from skin-safe platinum silicone rubber. This initial mold can be relatively weak but flexible. A hard mother mold, also known as a jacket or matrix, is typically made of plaster or fiberglass which is created over the outside of the initial flexible mold to provide support. This mold is used to cast a copy of that part of the actor, in a hard resin or plaster type material to eventually use as a base for sculpting the prosthetic. This is considered a "positive" or life-cast.
Before sculpting the clay prosthetic over the positive, The positive must be prepared by adding "keys" or mold points along the edges of it, which are often added using clay or more plaster or carved into the life-cast, to make sure that the two pieces of the mold will fit together correctly. Often the life-cast will be given an additional border in clay or plaster in order to have an area free of detail and undercuts to add these keys. The entire life-cast with borders and keys included is then molded. This ensures a stable area with built in keys to sculpt the prosthetic over. This also provides the artist an easily duplicated copy, if needed. Multiple copies are typically used to make variations or stages of prosthetics or different prosthetics for the same actor.
Life-casts of full bodies and body parts are also used and reused as the basis for making fake body parts, severed limbs, and various "gore" type effects used in horror films or films where body parts are required.
The prosthetic required will be sculpted over the life-cast of that body part to become the design intended. For example, if the desired look is a pig nosed person, then the artist would sculpt the pig nose over the actor's real nose on the life-cast or positive copy. The edges of the clay should be made as thin as possible, for the clay is a stand-in for what will eventually be the prosthetic piece. Once sculpted, the new addition of the clay sculpted prosthetic part must be molded. Since the positive has been prepared with the additional border and keys, it actually becomes part of the prosthetic mold itself. Once molded, and clay removed, new mold cleaned out, the positive is one part of the mold and the new mold is the other side which has the negative of the newly sculpted prosthetic. This gives two or more pieces of a mold - a positive of the face or body part, and one (or more for complex molds) "negative" mold pieces with prosthetic sculpted in.
To make the new prosthetic, material is cast into the mold cavity (where the clay used to be). The prosthetic material can be foam latex, gelatin, silicone or other similar materials. The prosthetic is cured within the two-part mold. The prosthetic is carefully removed and prepared for painting and or application to the actor.
As the film/television industry continues to grow, so do the capabilities of the technologies behind it. Since the debut of newer technologies, many have feared that CGI (Computer Generated Imagery) will put practical SFX makeup out of business. CGI can be used to accomplish effects that simply aren't possible when working in practical effects.
Tom Woodruff Jr. and Alec Gillis, two experienced SFX artists from Amalgamated Dynamics near L.A., share what they see as the middle ground on the subject. In an interview, they explain that most movies use (out of necessity) a combination of practical effects and CGI. They see CGI as a tool that can be utilized in a positive or negative way, just like practical effects.[1]Tom Savini (an SFX artist known for his work in Dawn of the Dead and Creepshow) states: "They still use the make-up guys to design the creatures and that’s what they work from. I don’t think you’ll see make-up effects guys hanging out on corners with signs that say: WILL DO EFFECTS FOR FOOD."[2]
Moulage is a process in which makeup is used to simulate different wounds and trauma in order to prepare medical, emergency, and military personnel for what they could experience in the field and lessen psychological trauma.
Other real-world uses are to create real disguises for Government agencies such as the F.B.I., C.I.A., Department of Justice, used to infiltrate possible terrorist groups. Special effects artists can create and apply special effects makeup prosthetics to undercover agents to gather intelligence for combating international terrorism. Disguises let officers and agents move around as another person to complete undercover work without jeopardizing their actual identity.
Another real word use of prosthetics is the appearance of wounds to emulate death to be used by agencies such as the police departments to make someone appear as the victim of a murder during "hit or murder for hire stings." If a suspect hires a hit-man (killer) to murder someone, the police are able to stage a set of pictures or video to make the suspect believe that the "hit" or murder has been carried out. These situations are made to gather evidence on the suspect before the actual crime of murder has been committed.
