Eighteen-year-old N.Y.U.ster Rachel Helson has done some very impressive work for the Susan G. Komen Breast Cancer Foundation: she's about to produce her third benefit performance of The Rocky Horror Picture Show, this time on Broadway, with all proceeds going to the charity! And she's managed to recruit some A-list Broadway talent, too, like Neil Patrick Harris and Wicked's Kate Reinders. But that's not even the most charitable part. Helson, who the Times described today as "perky" (later: "Perky is almost too mild a word"), will also be generously donating her own time on the night of the performance, starring in the production as ingenue Janet Weiss. "Students at Tisch are by nature ambitious," said Tisch dean Mary Schmidt Campbell, adding that "in terms of the scale of her ambition, this rates up there 10-plus."
