From Get In Media
The key grip works for the director of photography (DP) and supervises the crew of grips responsible for camera equipment and accessories and anything associated with the camera’s operation and movement, as well as anything that cuts or diffuses the lamps set up by the gaffer’s crew. He or she attends preproduction meetings with the director, producers, DP, and location scout to determine what special equipment may be needed during the shoot, then works closely with the gaffer on-set to supervise the positioning of scrims, reflectors, and flags that diffuse light and create shadow. During the shoot, the key grip will also assign grips to oversee camera movements that require dollies or cranes, as well as managing set operations like the movement of wild walls. Once the set is built and has been photographed, it is no longer the responsibility of the construction crew, but the grip department. Because they are in charge of all rigging, the grip department is responsible for safety on-set, and the key grip can be taken to court if an accident happens.
On large productions the key grip will have a best boy grip (male or female), who is the second in command, and a crew of grips who are highly specialized in specific tasks: set ops grip, dolly grip, construction grips, and crane operator. On very small shoots, the key grip may function as part of the crew, but generally this is only a supervisory role—the heavy lifting and laying of track is left to the grips. Most key grips will have at least some of their own grip equipment. A key grip often has his or her own grip truck, and will rent it to the production he or she is working on.
Skills & Education
A college degree is not required in this role, but training is. A degree in film and television production can introduce you to the filming process, the use of grip and camera equipment, and the artistic theory of photography. As a key grip you need to be mechanically inclined, with an excellent understanding of light, color, and electricity. Most working key grips are members of IATSE (International Alliance of Theatrical Stage Employees), which offers apprentice-training programs. Working as a grip on union productions is the only way to make the move up to key grip. Commercial or residential construction experience is also useful toward this role, as many working in the grip department have made the leap to film and television production through friends and close contacts.
