Actress ISABELLA ROSSELINI insists having famous relatives can be disastrous, because directors have often been too intimidated to cast her. The Blue Velvet actress, the daughter of director ROBERTO ROSSELINI and actress Ingrid Bergman, believes nepotism never worked in her favour - especially after her marriage to GOODFELLAS film-maker Martin Scorsese. She says, "Directors always told me they were inhibited by me. "Not only was my father the director Roberto Rosselini but also I was married to Martin Scorsese, which floored them."
