When, a few years ago, Tinseltown declared 3D as the future once again, the studios began rethinking every thrill ride they had lined up for release, hoping to cash in on the stereoscopic craze. And, thanks largely to the success of Avatar, 3D was indeed a golden goose. For a while.
But unless you're dealing with a hatchet-swinging splatterfest or a heartwarming tale about a magic Frisbee, there's rarely any need for 3D.
Which makes you wonder what the hell James Cameron felt he could bring to his 1997 box-office champ by re-releasing it in 3D. Besides a few extra million at the box office.
"I don't think James would sign up for anything unless he thought he could do something unique with it," offers Titanic's leading lady, Kate Winslet. "It's not like the guy needs the money. And he's been at the forefront of technology for just about all of his career -- both on land and underwater, let's not forget -- and I wasn't surprised at all to discover that he was drawn to rework Titanic in 3D."
That Cameron spent $18m on the 3D conversion suggests a man concerned with the quality of what he referred to as the "turbo-charged" version of Titanic, but Winslet recognises the weariness that some cinema-goers might feel.
"I'm a little reluctant too, when I know a film is in 3D," she nods. "Only because, there are those filmmakers who are truly engaged with it, a good example being Martin Scorsese with Hugo, but then there are a whole plethora of films where the 3D was done in post-production merely as a commercial consideration.
"You kinda know before you go in which films were made with tender, loving care and which ones were made with an eye purely on the box office."
For Titanic, the conversion took 60 weeks and 300 artists. Cameron has argued the point that there would be a whole new generation out there who never saw Titanic on the big screen. The film was the biggest grossing movie of all time -- until Avatar came along 12 years later and knocked Titanic off its perch.
Still, Winslet has seen Titanic before. So, is the 3D conversion a whole new experience?
"It's a whole new experience for me, just watching a film I made so long ago," she smiles. "I tend to avoid looking back too often, because all I ever see are the mistakes. The moments where, I feel, I played the scene badly, or missed a beat, or just didn't think of the right way to play the scene -- a better way that's now shouting at me from inside. And that American accent! Sheesh.
"That said, it's an incredible experience to be in an audience, and feel that communal sense of being on this journey together. Whether it's laughter or tears, there's something approaching levitation that happens with an audience when you're all feeling the same emotion. It's not only shared but multiplied ... "
The one scene Winslet won't be sharing with audiences is the steamy rumpy-pumpy-in-the-back-of-the-car moment.
"Oh, that's something I just can't watch," she offers. "Imagine what that's going to look like in 3D! I have enough trouble looking at myself trying to be sexy in 2D. In 3D, I'll probably end up crawling down under my seat."
Which will no doubt feel very 3D for anyone sitting behind Winslet.
