A little kid kicked A-Team butt at the box office.

Not just any kid — Will Smith’s 11-year-old son, Jaden, in a remake of “The Karate Kid,” which topped weekend movie sales, according to studio estimates.

The “Karate Kid” remake earned an estimated $56 million during its first three days, vanquishing “The A-Team,” a distant No. 2 with $26 million. Both films had been expected to vie for the top spot, each in the $30 million range.
