TOKYO — Distrib Gaga has taken an exclusive option on the film rights to Capcom’s samurai computer game “Onimusha.”Move follows the enormous success of another Capcom game-turned-pic, the Milla Jovovich starrer “Resident Evil,” which topped Japan’s B.O. for three weeks earlier this year and earned $20.7 million. “Resident Evil” was distributed in Japan by Gaga competitor Amuse Pictures. “Resident Evil” producer Samuel Hadida is attached to develop “Onimusha” for the bigscreen, together with Gaga. Some 4.6 million copies of the “Onimusha” game series has been sold worldwide. Gaga hopes it has secured a potential hit to rekindle its dwindling box office fortunes.
