SPEED DIAL JANE ROSENTHAL

Call me old-fashioned," says Jane Rosenthal, Robert De Niro's partner at Tribeca Productions, "but, for business, I tend to respect a lot of the people I work with, so I prefer not to call them from the cell thus avoiding one of the don'ts of cell-phone etiquette. For the same reason, Rosenthal, an avid supporter of the Democratic bid for the White House and Senate, doesn't have the vice president a push button away. However, speed dial is the tool of the working wife and mom. "I call home to check on my kids the most during the day," she admits freely, and the cell of "the man I met in a business meeting over a real-estate deal," husband Craig Hatkoff, ranks No. 1 on the display of her Motorola V8160. (Office and home she knows by heart.) And although she can crunch the numbers of a movie budget with ease, she cannot readily get her mind around other people's mobile numbers. Therefore, by virtue of her 12-year business association with Robert De Niro, "Bob Cell" ranks No. 2 and CAA agent Bryan Lourd No. 3, proving that some transcend the no-business rule. The director Jay Roach (No. 6) is listed because his comedy Meet the Parents, starring De Niro and Ben Stiller, is being released this month. Stiller and De Niro "are great together," enthuses Rosenthal. "They just really work off each other. Bob always brings out the best in the people that he's working with." Daily conversations with playwright and pal Wendy Wasserstein (No. 12) concern "baby stuff, nanny stuff, and"—here Rosenthal pauses briefly, allowing one to absorb the full impact of her admission—"shoes." Each will happily use her speed dial to negotiate the logistics of a binge at Bergdorf's shoe department. That's when etiquette is thrown out the window.
