Up floated to the top of the box office in its opening weekend, filling its balloons with $68.2 million. That's good enough for No.3 on the animation giant Pixar's all-time list, trailing only Finding Nemo (which opened with $70 mil) and The Incredibles.

Up was unanimously trumpeted by reviewers, and rightfully so. The action-comedy, about an elderly man (voiced by Ed Asner) who sets his house aloft on a journey to South America, was truly wonderful, remarkably original and teeming with heart. (When he flips through the photo album near the end? Awwww.) Plus, my kids loved the talking dogs. Squirrel!

Last week's box-office champ, Night at the Museum: Battle of the Smithsonian, slipped to second place with $25.5 mil.

The weekend's other major release, Sam Raimi's critically hailed Drag Me to Hell, opened at No. 3 with $16.6 mil.

Rounding out the top five were Terminator Salvation ($16.1 mil) and Star Trek ($12.8 mil, $209.5 mil-to-date), which became the first 2009 release to pass the $200 million mark.
