Walt Disney Animation Studios continues to strike it big in Northern American theaters as its 3D comedy adventure flick "Zootopia" bags an estimated $50 million at the box office in its second week following its opening weekend victory.

This brings the animated film's total domestic earning of $142.6 million to go along with its $288.7 million from ticket sales overseas.

Coming in at a respectable second is the J.J. Abrams-produced science fiction thriller "10 Cloverfield Lane," which took in $25.2 million in North America during its opening.

The film tells about the story of a young woman who suddenly is forced to live in an underground bunker with two other strangers after an apparent bioterrorist attack decimated the world above. When she finds out that the man who took her in was dangerous, she tries to make a run for it only to discover that the attack occurred as a result of an alien invasion in the United States.

While the story was originally titled "The Cellar" in earlier drafts, it was later turned into a spiritual successor to Abrams' 2008 monster flick "Cloverfield."

"10 Cloverfield Lane" stars Mary Elizabeth Winstead, John Gallagher, Jr., John Goodman and Bradley Cooper.

20th Century Fox's "Deadpool" occupies the third spot at the box office, posting a solid $10.8 million worth in ticket sales. It has already made $328.1 million over a five-week period.

Sacha Baron Cohen's "The Brothers Grimsby" also made its debut over the weekend, but has failed to live up to expectations so far, making a measly $3.15 million in more than 2,200 theaters. This is considered to be the lowest opening for a film developed by Baron Cohen.

It features Baron Cohen as the bungling Nobby Butcher who is in search of his long-lost brother Sebastian Graves (Mark Strong), who turns out to be one of MI6's top agents. Graves is out to save the world from the evil plot of his enemies, but he's going to rely on his brother to help him out.

Its cats include Isla Fisher, Rebel Wilson, Ian McShane and Penélope Cruz.

The spy comedy was reportedly given a budget of about $80 million by Sony Pictures, which took over production from Paramount. Despite receiving an audience rating score of A- from CinemaScore, the film suffered from limited marketing from the studio.

Other films that opened over the weekend include Lionsgate's romantic comedy "The Perfect Match," which made about $4.2 million in less than 1,000 theaters, and Focus Features' "The Young Messiah," which took in $3.4 million in a wider release.
