In 1997, millions of people and audiences worldwide were astounded by James Cameron's masterpiece Titanic.  15 years later the Academy Award winning director's obsession with the doomed vessel continues.   Here's why we think Titanic is once again worth a trip to the theater.

1.  It's in 3D and IMAX.  You may have seen the RMS Titanic sink a hundred times before, but you've never seen it like this--larger than life and headed straight for you.

2.  Iceberg's are cool.  And the Northern Atlantic glacier that took down a ship once dubbed unsinkable is the most notorious of all time.

3.    Jack and Rose.  Titanic was all water and broken wreckage, but at it's heart the movie's fictional story line created one of the greatest love stories of all time.  Plus Leonardo DiCaprio and Kate Winslet were just teenagers then.  See how far they've come, they're much better looking NOW.

4.  'My Heart Will Go On' by Celine Dion.  It's been 15 years so it's now acceptable to be nostalgic about it and admit that it takes you back in time.

5.  To honor the memory of those who were lost on that fated night nearly 100 years ago on April 15, 1912.
