Please help me ID this movie. I can't remember if it was a foreign movie or American. It's about a young artist (man) who falls in love with a much older woman (long white hair if I remember correctly. I remember she was VERY pretty for her age. Thin and frail. He paints her in the nude at one point. And before she dies ( I think she had cancer or something), or more exactly before he helps her commit suicide, she decides to leave him her studio or house. But her relatives ask for it back, claiming it's their right, and accusing him of killing her. I didn't watch it from the beginning so don't have more info.
