The kids showed their power at the box office this weekend, when they helped Pixar's new animated action comedy "Up" take the #1 seat by a landslide.

"Up" took flight with a $68.2 million opening weekend, maintaining a perfect box-office track record for Pixar Animation, whose 10 films all have been commercial and critical hits, according to the Associated Press.

The film has the third-best opening for a film from the Disney-owned company, just behind the $70 million debuts for "Finding Nemo" and "The Incredibles." Last summer's "WALL-E" debuted with $63.1 million.

"Up" took over the #1 spot from from last week's winner, "Night at the Museum: Battle of the Smithsonian," which slipped to second-place with $25.5 million. After 10 days, the comedy, starring Ben Stiller, has raked in $105.3 million.

This weekend's other new wide release was the horror flick, "Drag Me to Hell," which opened at #3 with $16.6 million. The Sam Raimi directed film is modest compared to some of his other films, including his three "Spider-Man" movies all of which had blockbuster opening weekends.

"Terminator Salvation" dipped from #2 to #4 in its second weekend, earning $16.1 million.

"Star Trek" landed at #5 with $12.8 million,d passing the computer-animated "Monsters vs. Aliens" as the year's top-grossing movie so far. In the U.S., it's sold $209.5 million in ticket sales, becoming the first 2009 release to cross the $200 million mark.

The Wayanas Brothers outrageous comedy, "Dance Flick", fell to #7, earning another $4.9 million after a modest $11.1 million opening last week.

At #8 was "X-Men Origins: Wolverine" with $3.9 million, "Ghosts of Girlfriends Past" came in at #9 with $1.9 million; and Beynce's "Obsessed" rounded out the top 10 with $665,000.

According to the AP, overall weekend revenues were at $167 million, virtually even with the same period last year. Total revenues for 2009 rose to $4.1 billion, up 13.7 percent. Movie attendance was about 11 percent ahead of last year's.
