When asked about his reason for taking on the role of Daruma, Beat Takeshi revealed that MOZU's story resembles the American suspense dramas which he likes and that because Nishijima is his radio programme fan and they have a common interest in mathematics, he believes that it will be a very enjoyable experience to take part in this movie. As for Nishijima, he worked together with Beat Takeshi in his 2002 movie "DOLLS" and is looking forward to their collaboration again. Iseya commented that he thinks that he sees the role of Takayanagi as a very challenging role for him while Matsuzaka is very excited about taking on an evil role this time.
Filming of the drama began in late March but due to restrictions on bombing and car action scenes in Japan, the cast and crew had to go to the Philippines in April for a month for the filming. They did 4 bombing scenes at a big Manila market and used a total of 1,500 bullets during the period.
