Jackie Chan and Jaden Smith in 'The Karate Kid' (2010)Will Smith has been the savior of the summer box office more than a few times; now it's his son Jaden's turn.

The upset victory of Jaden Smith and Jackie Chan's reboot of 'The Karate Kid' over fellow '80s update 'The A-Team' was not only unexpected but came at such a huge margin ('Kid' debuted at an estimated $56 million, more than twice the $26 million opening for 'Team') that it made the spawn of Smith look like a new box office hero, capable of defeating rival franchises - and the current summer box office slump - with a single roundhouse kick. Jackie Chan and Jaden Smith in 'The Karate Kid' (2010)Will Smith has been the savior of the summer box office more than a few times; now it's his son Jaden's turn.

The upset victory of Jaden Smith and Jackie Chan's reboot of 'The Karate Kid' over fellow '80s update 'The A-Team' was not only unexpected but came at such a huge margin ('Kid' debuted at an estimated $56 million, more than twice the $26 million opening for 'Team') that it made the spawn of Smith look like a new box office hero, capable of defeating rival franchises - and the current summer box office slump - with a single roundhouse kick.

'Kid' far exceeded the $25-$30 million predictions everyone had made, including its distributor, Sony. Despite the wails of fans of the 1984 'Kid' who thought the new version strayed too far from the original (a much younger star, a more exotic setting, kung fu instead of karate), the reboot attracted kids and families who had already seen 'Shrek Forever After' (or were still balking at its 3-D surcharge). 'Kid' averaged $15,288 per screen, more than any other movie in wide release. Budgeted at just $35 to $40 million, the film has already grossed more than it cost, and it hasn't even opened yet overseas, where Chan's global star power should ensure similarly huge sales.

'A-Team' had been expected to finish slightly ahead of 'Kid' in the $32 to $37 million range, since it had somewhat more star power (including Liam Neeson and Bradley Cooper) and more adult appeal than 'Kid' or 'Shrek.' But it looks like audiences aren't buying '80s-style tongue-in-cheek action this year, having already ignored 'The Losers' and 'MacGruber.'

Three-time champ 'Shrek' finally gave up its title and settled for third place with $15.8 million. Losing just 38 percent of last week's business, it crossed the $200 million mark and then some, for a total of $210.1 million to date.

Last week's top newcomers fell two slots each. 'Get Him to the Greek' dipped from No. 2 to No. 4, and took in another $10.1 million, down 43 percent from last week. 'Killers' went from third place to fifth place, losing 48 percent of last week's business with an $8.2 million finish.
