Ooizumi expressed anticipation at making a good and interesting movie which led Matsuda to tease him that it took that long because Ooizumi was too busy to do Part 3. Not to be outdone, Ooizumi asked Matsuda if he will be OK juggling the filming of TBS Winter 2017 drama "Quartet" with the movie which the latter promised that it will be fine since he can play the violin and do action scenes at the same time. However, Matsuda did admit that he has been so busy that he hasn't read the movie's script yet. Upon hearing this, Ooizumi "scolded" Matsuda for taking on a drama during this period even though he kept telling Ooizumi that he wanted to do a new Tantei movie. He jokingly suggested that Matsuda should quit from the drama and make it become a trio instead.
In line with the theme of the movie, Kitagawa was asked about what secret she would not like the detectives to know and replied that she wouldn't want to let people see how she looks like at home. She also revealed that she had only met Ooizumi and Matsuda for the first time just 15 minutes before the press conference but she has been a fan of their movies so she is happy to be a part of the new sequel. Kitagawa will be playing the owner of a modelling agency who spins the detective around her little finger.
The movie is expected to be shown in cinemas this winter.
