Fans crash 'Titanic 3-D'

Paramount Pictures claims that "multiple servers" crashed due to fans signing up for tickets to the Feb. 14 sneak preview screenings of "Titanic in 3D," to be held in more than 50 U.S. cities and in 13 countries around the world. The tickets are now sold out, Paramount reports.

The 3-D version of James Cameron's 1997 box-office record-breaker is due for release April 6.
