Helmer Masayuki Suo is prepping a new film 10 years after the release of his worldwide hit “Shall We Dance?” That pic was released in the U.S. by Miramax in 1996 and remade as a Richard Gere-Jennifer Lopez starrer in 2004.

New project “Sore Demo Boku wa Yattenai” (Even So, I Didn’t Do It) details the arrest and trial of a man accused of molesting a woman on a train. Shooting begins in May for a 2007 release by Toho.

Inspired by a true incident, the film is Suo’s first serious drama after a successful career making comedies, including “Shall We Dance?,” “Sumo Do, Sumo Don’t” and “Fancy Dance.”

Suo spent three years researching the script, including visits to courtrooms and interviews with judges and prosecutors.

Pic will star Ryo Kase as the salaryman hero. His credits include Kiyoshi Kurosawa’s “Bright Future,” Hirokazu Kore-eda’s “Nobody Knows” and Clint Eastwood’s WWII pic “Red Sun, Black Sand,” set for release in December.
