Sharon Stone has been given the ultimate compliment from the real-life grandchildren of her new movie character - she reminds them a lot of their grandma. The actress portrays Linda Lovelace's mother in the new biopic of the porn star-turned-feminist, and the X-rated actress' kids have given the role a big thumbs up. Lovelace director Rob Epstein says, "They felt Sharon's performance as Dorothy really captured their grandmother. "The thing most personally moving was, after seeing the film, Linda's daughter said that neither she nor her brother, Dominic, could read Linda's book - because it's so graphic and so disturbing - but now they could show this movie to their partners, so they could understand how important their mother was to them." And actress Amanda Seyfried has also poured praise on her movie mum, revealing she wouldn't have been quite as comfortable on set if it wasn't for Stone. She tells WENN, "I don't know if it would have gone quite as smoothly if we hadn't started with our scenes together, because I was terrified the first day. It would have been different (if) I didn't have her maternal energy. It was amazing."
