"Tron Legacy" enters North American Box Office with a blast. It rakes in an estimated $43.6 million on its first weekend and snatches the top spot from "The Chronicles of Narnia: The Voyage of the Dawn Treader" which could only secure the champ title for a week. According to Rotten Tomatoes, the movie owes it to nation's movie critics who recommended it.

The movie, which lures fans of 1982 "Tron", has 55|percent| of the audience consisting of couples. "All the fans of the first movie are bringing a girlfriend or wife to share the experience with. But the blend of the audience will get younger," Disney worldwide president of marketing Chuck Viane says.

"Yogi Bear", which also made its debut late last week, opens to an estimated $16.7 million, which is below the expected $20 million cume. Still, the family animation could hope for strong midweek traffic as the Christmas session gets into full swing.

Meanwhile, there is little hope for "How Do You Know" to gain advantage from the holiday season. The romantic comedy which stars Reese Witherspoon and Owen Wilson debuts on number eight with an approximately $7.6 million.

The third position of the chart now belongs to "The Chronicles of Narnia 3" with an estimated $12.4 million. "The Fighter" jumps from the nineteenth to the fourth with an additional $12.2 million after it opened wider in U.S. theaters. "The Tourist" drops from the second to the fifth with an estimated $8.7 million.
