The Oscar-winning actress is very excited about seeing her most famous movie come back to the big screen in three dimensions but, like many parents, her kids Joe, eight, and 11-year-old Mia don`t care about their mother`s career. When asked what her children think of the film`s re-release, she replied: "They`re actually really not interested. But they are intrigued, I think, would be fair to say." Kate - who become a worldwide star following the 1997 movie`s staggering box office success - is very interested in seeing the completed version but she is nervous she won`t like her performance. The 36-year-old star told the USA Today newspaper: "I`m sure I wasn`t really a very good actress. Seriously, we are talking about something that happened 15 years ago. It is a very long time ago. I`ve learned so much, and I`ve changed as a person so much since then. It is really quite weird. Can you imagine anything stranger? It`s going to be like famous all over again, `Titanic` all over again!" Kate has so far only watched 17 minutes of the 3-D version of James Cameron`s blockbuster and the first thing she noticed was how "skinny" her co-star and friend Leonardo DiCaprio is in the film. Referring to her brief viewing, she said: "I was literally like, `Oh my god, make it stop! Is that me? Oh my god, that`s me. Block my ears, somebody! Somebody club out my senses. Make it stop!` "And Leo looks so young and so skinny!"
