As of this past weekend at the movies, it's probably no longer possible to say songwriter-performer-producer Ali Dee is deploying his unique skill set in obscurity.

This simple discipline saves us from leaning too hard into a cornball line about how he's Hollywood's secret soundtrack weapon, while his dad made secret weapons (more of that further down). However you look at it, the 37-year-old, New York-based musician is a phenomenon—an artist with a hand in wide releases Iron Man, What Happens in Vegas and Speed Racer.

A bit earlier this spring, Ali did a soup-to-nuts job on the Alvin and the Chipmunks soundtrack, helping propel the movie to $357 million in worldwide box office and setting the soundtrack on a course for platinum sales.

It's not as if Ali, whose real surname is Theodore, sought out the attention. Your correspondent happened to have a friend who's in business with him, and the steps from "telling the world abut Ali—good idea" to actually wrangling the workaholic into an interview were many and varied.

Once he took the call, Theodore was everything his colleague Dave Parker (who works with Format Entertainment founder Dave Jordan in music supervision for films) had promised.

"Quite frankly," says Parker, who normally would be the middleman in a soundtrack deal and duly pen it in on one of his two big whiteboards full of Ali projects, "the studios will often call Ali directly because he's that charismatic guy. He's not the wallflower studio guy who's sitting in a dark room somewhere, making genius stuff, but nobody ever really knows who he is. When he walks into a room, he's the guy you want to know."

It's what Hollywood types call "good in a room."

But the real point—because nice alone has never cut it in Hollywood—is that Ali is very, very good in a studio. Although his six-room production facility on Manhattan's West 26th Street is stuffed with musical instruments, he claims to be "not especially good" on any of them.

He is, however, a master of his wide-ranging address book (thus he speedily assembled an array of international performers for the Speed Racer title tune) and a fair hand at the mixing board. What Ali does best is use his ears to run on instinct: "Typically if I don't hear a direction of where to take something right away, then I probably never will," he says. "And more often than not, when I hear something, it comes to me right away what to do with it."

That kind of quick traction, mixed with what Parker sees as an almost unerring insight into what a studio film music division needs in order to tell (and market) a film's story, is what "separates him from the pack."

He's a unique guy in that he's a bit of a chameleon music-wise, so he can service a wide variety of needs for music for film and TV. And he's got a system set up where he can deliver a phenomenal amount of music at a very high quality at a very quick pace.

Thus Warner Bros. and producer Joel Silver, with the film speeding toward its May 2 date in the marketplace (and perhaps realizing it would need some help in that arena), had been fruitlessly in search of the right update for the title song.

"Basically they were in a jam," says Ali, with a characteristic mix of modesty and the-doctor-will-see-you-now self-confidence. "They were saying 'We need help. We have this big movie we're trying to put out and we cannot get a version of this thing right.' I took the challenge on, and when I went to the original version I had a vision of exactly where I heard the track going. I didn't want to make it 'mine.' I wanted to make the track great for what it was."

He did so within a matter of days, using mostly acquaintances from the New York music scene (though a French singer was recruited from Toronto and a pair of Japanese artists recorded their vocals in Japan).

Theodore had assembled a track that the studio was ecstatic to spot through the film and use over its end titles.

That process was more rushed, but otherwise similar to his work on the Alvin soundtrack. In that case, says Fox senior vice president of film music Mike Knobloch, Ali got handed a similar updating chore. Such time-honored (and thus resistant to updating) fare as the Christmas-themed "The Chipmunk Song" would need to be re-recorded and reinvigorated with the mash-up of hip-hop beats and poppy instrumentals that Ali can churn out in amazingly short order.

At 672,000 units sold (about 89,000 of those via digital downloads, mostly on iTunes), the soundtrack has become a "nice revenue stream" for Fox, says Knobloch, who further credits Ali with never holding the studio up for an onerous share of the proceeds. "He's smart enough to know we'll make it up to him on various projects over time."

"We used to think we kinda had him to ourselves," says Knobloch. But aware that Ali recently completed work on the soundtrack for Warner Bros.' Sex and the City and has pretty well filled those whiteboards in Parker's office, he'll be putting dibs on Ali's time well in advance henceforth.

Theodore came to show business honestly, growing up in Manhattan as the son of a mother, Lee (nee Becker), who was a Broadway choreographer and briefly engaged to Jerome Robbins. His father Paris Theodore, who succumbed to M.S. in November 2006 at age 63, was a legend in several spheres. Paris was nine years old when he portrayed one of the Lost Boys (Nibs) in the famous 1955 Mary Martin television production of Peter Pan. He was simultaneously an abstract painter and an independent operative for (as far as can be verified by Ali and various casual historians of the era) the C.I.A. and/or the N.S.A.

Firearms-savvy from that work, he started his Seventrees company in 1966 and became a supplier first of quick-draw holsters, then of a legendary concealable handgun, based on a Smith & Wesson Model 39. The gun was storied enough among spooks to replace James Bond's Walther PPK in the post-Ian Fleming Bond novels.

Although Ali remembers stumbling gratefully into soundtracks after 15 years of relative scuffling as a recording artist, he squeezes time in with his wife and son as often as he can. Right now, though, he's something of a studio rat.

"I've become busier than ever in the last six months, I'm willing to do the hustle. I never want to not work. I wake up every day happy to get to it."
