Internationally renowned actress, model, and individualist Isabella Rossellini is charm personified. She has a supporting role in Alice Rohrwacher's new import La Chimera,which opens in theaters March 29, and recently completed two seasons of Julia, playing Julia Child's longtime friend and cooking colleague. She also carries with her the torch lit by her famous parents, Ingrid Bergman and Roberto Rossellini and does so with grace and ease. Leonard and Jessie only had a half-hour with her but were happy to have had the opportunity.
