War Room is a video game version of a fictional nuclear defense that was programmed by Robert S. Harris in 1983 for the ColecoVision.
The War Room (1967/68-2002), by Wally Hedrick (1928-2003), consists of eight canvases approximately 5 feet wide and 11 feet tall, all painted a deep black. Hedrick referred to these canvases as "wounded veterans". These canvases are bolted together to create a freestanding square room that could be entered via a small door in one of the canvases, thus creating an architectural painting. The black painted surfaces of the canvases face inward and the backs of the canvases face outward.
The War Room is an 'environmental' painting where the viewer enters a small enclosure of painted blackness. The viewer is left to consider the encompassing darkness and contemplate the vacuity that this space creates. Hedrick refused to ignore the war and instead created a work of cultural and political significance. After the Vietnam War ended he repainted these canvases black in protest of the Gulf War in 1992 and the Iraqi war in 2002.
During this time, Hedrick was accused of stealing paintings, including a canvas by Clyfford Still, from the San Francisco Art Institute, where he was teaching, then either painting them black or painting his own iconoclastic pictures over them.
The "War Room" is a significant item of Bay Area art history.
War Room is a 2015 American Christian drama film directed by Alex Kendrick and co-written and produced by Stephen Kendrick. War Room is the Kendrick brothers' fifth film project and their first film project through Kendrick Brothers Productions. Provident Films, Affirm Films and TriStar Pictures partnered with the Kendrick brothers to release the film.
Regarding the title of the film, director Kendrick says "We called it 'War Room because, like the military, we should seek God for the right strategy before going into combat. By combat, I mean daily issues we face in our culture." The film was released in North American theaters on August 28, 2015, and received generally negative reviews from critics, but became a box office success and a sleeper hit. Regarding War Rooms box office performance, CNN said "some might call it a faith-based David versus the secular Goliaths in the entertainment industry".
