THE HUNGER GAMES vs. TITANIC 3D at the box office … so far, it’s a very close race!

"The Hunger Games" still looks to be in good shape to finish atop the charts for the third consecutive weekend, but it will have to beat out newcomers "American Reunion" and "Titanic 3D," which are both proven strong openings.

Combined, the first three titles in the American Pie series grossed more than $650 million at the worldwide box office

From Paramount and 20th Century Fox, Titanic 3D opened Wednesday -- the 100th anniversary of the sinking of the real-life Titanic -- and grossed a strong $4.7 million (including Tuesday evening previews). The release also is opening in 84 foreign territories.

Lionsgate's Hunger Games remains a box office goliath, and has now earned north of $262 million domestically. It should cross $300 million by early next weekend, and possibly by the end of the weekend if business is particularly strong.
