TOKYO — Helmer Hirokazu Kore’eda has announced his next pic, “Kiseki” (Miracle), a drama starring the tween comedy duo Maeda Maeda.

Shooting will start on Sept. 18, with release skedded for early summer 2011.

The Maedas — real-life brothers Koki, 11 and Oshiro, 9 — play siblings separated by the divorce of their parents, with one living in Fukuoka and the other in Kumamoto — cities on Japan’s southern main island of Kyushu. Hearing that a miracle occurs the instant a “Tsubame” bullet train from the north and a “Sakura” bullet train from the south pass each other, the two boys start making plans.

Japan Railways group companies JR Kyushu and JR East Japan are helping to develop and underwrite the pic, though the budget and distrib have not yet been disclosed.

Kore’eda’s last pic with child thesps as leads was “Nobody Knows,” a Cannes competition entry in 2004 for which star Yuya Yagira, 14, won a best actor prize.
