Sci-fi epic TRON: LEGACY has powered its way to the top of the box office grid, scoring $43.6 million (£29 million) in its opening weekend in the U.S.
Jeff Bridges returns to his role as video game hacker Kevin Flynn in the new Disney 3D movie, reprising his character from the original Tron in 1982.
Family adventure Yogi Bear, starring Anna Faris and featuring the voices of Dan Aykroyd and Justin Timberlake, cowered behind Tron: Legacy in second place, debuting with $16.7 million (£11.13 million), while The Chronicles of Narnia: The Voyage of the Dawn Treader slips to three with $12.4 million (£8.27 million).
Hotly-tipped Oscar favourites The Fighter and Black Swan continued to draw in the crowds with strong takings of $12.2 million (£8.13 million) and $8.3 million (£5.53 million), respectively, placing the films in fourth and seventh in the top 10.
Meanwhile, Reese Witherspoon and Owen Wilson's new romantic comedy failed to woo movie-goers this weekend (17-19Dec10) - it scrapped in at number eight with a gross of $7.5 million (£5 million).
