While their mother and daughter characters don't exactly see eye-to-eye in the Oscar-winning film classic "Titanic," Frances Fisher said she and fellow star Kate Winslet feel a strong family connection when it comes to reuniting to celebrate the film.

In a recent interview to discuss "Titanic's" debut Monday on Blu-ray, Fisher told me how proud she remains of her big-screen daughter and her achievements since the film made history in theaters 15 years ago. The two reunited when they joined writer-director James Cameron as well as several other cast and crew members at the world premiere of "Titanic 3D" in London in March.

"When I saw her on the red carpet, she turned to me and went, 'Mother!' The lovely thing about working with actors is that you have an unspoken connection that continues no matter how many years go by," said Fisher. "We get right back to that moment (when we worked together) when we see each other again."

Fisher said she's still moved by her memories aboard "Titanic," and particularly of the man at the helm of the monolithic blockbuster, James Cameron.

"I just think he's a genius. I love him as a person, and I love him as a writer, director and producer," Fisher said.

The release of the film on Blu-ray (Paramount Home Entertainment) comes just months after the commemoration of 100th anniversary of the sinking of the real Titanic, which happened in the North Atlantic April 15, 1912. In addition to the epic film, the Blu-ray release has more than six hours of special features, including 30 deleted scenes and 60 production featurettes.

Fisher plays Ruth DeWitt Bukater, the strict, traditional mother of Rose DeWitt Bukater (Kate Winslet) -- who enters a forbidden romance with Jack Dawson (Leonardo DiCaprio) on the doomed maiden voyage of the RMS Titanic. Ruth wants Rose to marry blue-blood Caledon "Cal" Hockley, while Rose prefers to be with Jack, the man from wrong side of the tracks.

Although it was a very intense shoot, Fisher said she still managed to have her share of fun on set. But then again, she added, playing Ruth was fun, no matter how reserved of a character she was.

"When the cameras roll, you just get into the character," Fisher said. "In a way, it was one of the easiest roles I've played. No matter what state of mind I came to the set in, when I got my hair put up and my corset on, I became Ruth."

As it turned out, Fisher never realized how important the corset became to playing Ruth. The funny thing is, it had nothing to do with physical appearance.

"At the end of the filming, I went in and looped a couple of lines. A couple days later, Jim called me and said, 'What happened to your voice? You don't sound the same. I'm sorry I'm going to have bring you up to Skywalker Ranch in Northern California to re-loop the lines -- and bring your corset,'" Fisher recalled.

"So I spent a week on the ranch, put on the corset, looped my lines and I was back in character again. Jim could hear the difference in my voice," Fisher added. "He could hear the difference of somebody in a corset and somebody who is not. That's how specific and brilliant he is."

While Cameron has earned a reputation as a task master on set, Fisher said never minded the high energy the filmmaker brought to "Titanic." One important thing Fisher discovered was that as focused he was at the task at hand, he was always willing to let his actors bring something to their parts.

"He is so focused, so driven and so specific with wants, and it was lovely to work with a director who knows what he wants. Yet he gives you the freedom to it within certain confines," Fisher said. "He would always say, 'Try it again. Try it again.'

"In the lifeboat scene, I did something that was not in the script and he said, 'Oh my God, that's good. Bring the camera over here and do that again. Let's try to catch that,'" Fisher added. "So, within the structure, he was totally open to actors bringing more. It was a fabulous experience."
