Much has changed since James Cameron's epic movie Titanic premiered in 1997 and on VHS in 1998 and now with the 2012 digitally remastered release of Titanic 3D. However, the faces of the film - Kate Winslet and Leonardo DiCaprio - haven't aged a day in 15 years, as seen in photos on the red carpet.

Winslet, 36, and 37-year-old DiCaprio, who was not present on the red carpet held at the Royal Albert Hall in London, haven't aged a day when comparing photos from the 1997 premiere and present day. Director James Cameron in addition to villain Billy Zane were also in attendance on the red carpet.

Titanic 3D, which arrives in theaters April 4 before the 100th anniversary of the sinking of the Titanic on April 15, 1912, took 60 weeks to adapt into 3D for the big screen, employing some 300 production artists.

The 3D enriches all of Titanic's most thrilling moments and its most emotional moments. More than ever, you feel you're right there going through all the jeopardy that Jack and Rose go through, Cameron told the AFP.

The original Titanic grossed more than $1.8 billion worldwide, the second highest-grossing film off all time after James Cameron's other hit, Avatar, which brought in $2.7 billion. Titanic earned 11 Oscars including Best Picture and Best Director in addition to thrusting then unknown DiCaprio and Winslet into the limelight.
