to Wallace's upcoming book, "The Billionaire's Vinegar: The Mystery of the World's Most Expensive Bottle of Wine."

The book, by the former Philadelphia magazine writer and executive editor, won't be out until May 13, from Crown Publishing, but Wallace's literary agent, Larry Weissman, works with a film agent, Sarah Self at the Gersh Agency, on developing movies.

Wallace says Todd Black and Jason Blumenthal of Escape Artists, which optioned the rights in conjunction with Smith's company, told him they only buy stuff they plan to make.

The author declined to reveal what he was paid for the option on his book about the 1985 sale, to Christopher "Kip" Forbes, of a $156,000 bottle of Bordeaux, said to have been owned by Thomas Jefferson. The seller, Hardy Rodenstock, was later sued by another billionaire, Bill Koch, who also bought some bottles.

"I wrote the book I wanted to write, and they'll make the movie they want to make. It'll be fascinating to see what they do with it," he said. If it's made, Wallace says, he would love a cameo.

"For me, the movie is the unraveling of a mystery that comes down to a guy who punked the wine world," Smith's fellow Overbrook-raised producing partner James Lassiter told Variety.

Wallace, 39, is currently freelancing for GQ. He's engaged to former Philadelphia Weekly columnist Jessica Pressler, who's now with New York magazine and blogging here.
