Leonardo DiCapriowas not looking to make a special effects-filled blockbuster. “I don’t like these gigantic, huge films,” said the actor when he was 22. MeanwhileKate Winslet, 21, not only lobbied to land her part of Rose Dewitt Bukater in director James Cameron’s big project, a love story set aboard the doomed RMSTitanic, she also leaned on DiCaprio to take the one he’d been offered, Jack Dawson. Only after shooting was well underway did it become clear that neither had known what they were in for. “Nothing could have prepared me for it,” Winslet toldLos Angeles Timesin 1997.
To be fair, no one could have prepared for it, asTitanic’s production was unlike any before, both in the scope of Cameron’s ambition and the cost and innovation needed to execute it. The mammoth effort involved 12 dives to the realTitanicwreck site, more than 450 computer-effects shots and multiple reproductions of the legendary ship, including one 90-percent-scale set constructed from 300 tons of steel. Along with much of the sprawling cast and crew, the film’s two stars would risk hypothermia in frigid water, and endure workdays that stretched to 20 hours. As production blew past deadlines and budgets, the Hollywood press predicted an expensive flop and compared the filmmakers' hubris to that of the owners of the real RMSTitanic, who had promoted the luxury ocean liner as “unsinkable.”
And then the movie opened.
The PEOPLE Titanic anniversary edition has two collectible covers.

Filled with photos, including some rarely seen on-set images, the new issue illustrates the beauty of the recreated luxury ship, from the china in the first class dining room to its passengers' glorious costumes. Also inside: How the stunning Heart of the Ocean necklace came to life and was auctioned to raise funds for one of Princess Diana’s charities.
“Yeah, I was a little bit obsessed there for a while,” Cameron tells PEOPLE. For now, he adds, “I’m not going back out to the wreck. I’ve done my investigation. We are putting all our data together with some of the other experts . . . to do a definitive publication on the marine forensics of the wreck.”

Given what he now knows, is there anything he would have changed in his original dramatized movie? Actually, not so much. Before filming began, says Cameron, “I spent a year researching because I wanted it to be as accurate as possible. I said to the team, ‘Guys, I want it to be like we went back in a time machine and filmed what happened.’ Of course, history is a bit elusive, and people had differing accounts. But we got pretty close, and nothing in our subsequent 20-plus years of investigation really upset anything major in the film. Could I, as a rivet-counting nerd, make a few tweaks to the movie? Yes, but I think we got it pretty right.”
