"Teeth" director Mitchell Lichtenstein and actress Jess Weixler flashed smiles in the Hamptons over the weekend. Weixler took part in the festival's Rising Stars program which identifies young actors it sees as, well, "rising stars." Weixler was also honored earlier in the year by Sundance for her role in "Teeth" (a film in which the teeth aren't found in the mouth), receiving a special jury prize.
