Disney (NYSE: DIS) soared to the number-one spot this past weekend with its new Pixar project, Up. The computer cartoon grossed roughly $68 million at domestic theaters as of early estimates, according to Boxofficemojo.

Disney took a lot of thunder away from News Corp. (NYSE: NWS) and its Ben Stiller comedy/fantasy Night at the Museum: Battle of the Smithsonian. That movie dropped to second place, taking in about $25 million.

It was a busy weekend at the box office. The Memorial Day holiday period is a time when studios try to set a good financial tone for their summer slates.

And it looks like News Corp. (NASDAQ: NWS) is the winner. The media company's Night at the Museum: Battle of the Smithsonian project, starring Ben Stiller, grossed an estimated $53 million at domestic multiplexes over the past three days according to Boxofficemojo. That was a good performance. The first Night at the Museum took in $30 million in its first three days of release back in Christmas 2006.

I was surprised that News Corp. came out on top. Did anyone out there think that Terminator Salvation, from Time Warner (NYSE: TWX), wouldn't be number one?
