Before he could play Kai a half-Japanese, half-English tracker who joins a famed band of ronin warriors in 18th-century Japan Keanu Reeves needed to get some hands-on time with a samurai sword. ''The katana is a two-handed sword, so the style and the basics were all new for me,'' Reeves explained on a soggy 2011 shooting day in a U.K. forest. ''For one thing, well, you really do need to hold on with both hands.'' 47 Ronin hits theaters one year after its planned release date and north of its $175 million budget. Under debut director Carl Rinsch, the production has endured reshoots, rejiggered F/X, and communication issues Rinsch needed a translator to talk to his mostly Japanese cast.
