John and Joan Cusack

Are you talking about Martian Child? I haven't read too many reviews, but I heard it was gettinga good buzz. And it supposed to be a movie that the whole family can see. It's about a widower who goes ahead and adopts a child like he and his wife planned. But the child is extrememly unusual and believes he is from Mars, and John Cusack's character learns to appreciate the differences this boy brings to him.
