He’d like to find such roles on the big screen as well, but current fare doesn’t lend itself to that possibility. Studios are too busy cultivating projects that pass what Brooks calls the “14-year-old/Korea test.”

“This is a generalization, because there are always good movies that pop up,” he said, “but for the most part movies need to appeal to very young people and to foreign people, and that’s not a dynamite combination for smart, intellectual comedy.”

Which is exactly what writer-director Brooks traffics in; not blockbusters but films with distinctly singular themes that have the added bonus of showcasing familiar actors in new, sometimes startling ways (think Debbie Reynolds as the overbearing parent in 1996’s “Mother”).

Besides 1991’s “Defending Your Life,” in which he and Meryl Streep explore a Brooksian vision of the afterlife, and 1985’s “Lost in America,” a skewering of yuppiedom, there’s his latest, “Looking for Comedy in the Muslim World” (2005).

His big-screen directorial debut was 1979’s “Real Life,” a prescient take on then-nascent reality TV - PBS, of all things, was the groundbreaker in 1973 with its “An American Family” documentary series. In “Real Life,” a filmmaker (played by Brooks) persuades a family to let him record their daily life and ends up a home-wrecker, literally; he burns their house down for a big finish.

His movies often tap into the zeitgeist or even foreshadow it, and his comedy was the same. One Brooks routine recounted in Zoglin’s book is “Rewriting the National Anthem,” in which open auditions are held for average Americans to warble their proposed replacement.

“American Idol” come to mind?

“I was friends with (singer-songwriter) Harry Nilsson, who said the job of the artist is to get way ahead and sort of scout,” Brooks said. “It’s like Davy Crockett.

“Not all entertainment does that. And, by the way, the entertainment that makes the most money is entertainment that doesn’t do that. Somebody said to me, ‘You’re always ahead of your time.’ I said, ‘Go to the bank. There’s no window there for that.’ ”

His next film project?

“I’m going to think of something done 10 years ago,” he said, joking.

Brooks said he enjoys the luxury of working in a movie without being responsible for it as a director. But the pull of a story idea, once born, often won’t let go. He turned down “Big” after his “Broadcast News” role because “Defending Your Life” had begun gestating.

He admits to routinely letting obsession take hold.

“So much so that when my wife and I bought a new mattress a number of years ago - and I’m not proud of this - but I think I knew more about mattresses than the guys at Sit ‘n Sleep,” Brooks said. “I went to a mattress store and in four minutes the salesman was afraid of me.”
