Box office: 'Elysium' blasts off to No. 1 debut

Neill Blomkamp's "Elysium" starring Matt Damon and Jodie Foster took No. 1 at the box office over the weekend with a $30.5 million gross. That was enough to lift it above "We're the Millers" starring Jennifer Aniston, Disney's "Planes" and "Percy Jackson: Sea of Monsters."
