James Cameron's "Avatar" is on a course to sink "Titanic" at the box office.
No. 1 for the sixth-straight weekend with $36 million, the 20th Century Fox sci-fi spectacle lifted its domestic total to $552.8 million, The Associated Press reports.
"Avatar" raised its worldwide total to $1.841 billion. That's $2 million shy of first place behind Cameron's last movie, the 1997 shipwreck epic "Titanic," at $1.843 billion.
"It defies all superlatives," said Chris Aronson, head of distribution for Fox.
The studio said "Avatar" has hit $1.29 billion in international ticket sales, passing the $1.24 billion mark set by "Titanic." The saga is also en route to overtake "Titanic" in domestic sales.
