Spielberg's iPad controlled Art Deco-styled screening room, Tom Cruise's 20-speaker audio system, Michael Bay's faux night time sky 49 seat screening room...the Wall Street Journal spotlights how and what Hollywood's biggest names use in their own homes (and some of the rules while screening).
The tech specs and excess isn't surprising, nor is the issue of house rules:
Food is one of the rare polarizing issues. Some strictly forbid it; Mr. Scorsese, who maintains a private screening room in his New York office, allows guests to bring in only water, according to a person close to the director. Sherry Lansing, who built a room in her home after leaving her post as chief executive of Paramount Pictures, says she allows both water and candy.
Average cost of these top of the line home theater (truly home theater, unlike what most of us call "home theater", myself included) is about $500,000. But someone like Michael Bay and his ode to his own ego can top $2 million or more, with screen sizes ranging from 14-18 feet.
