Kurosagi (映画 クロサギ) is a 2008 Japanese live-action film based on the manga series of the same name by Takeshi Natsuhara and Kuromaru. After the finale of the TV series in June, TBS received many questions about whether there would be a new season or a film. TBS decided to shoot a film, beginning in August 2007.

On March 8, 2008, the cast appeared on stage at Toho Cinemas Roppongi Hills. At the end of the conference, a guard with a suitcase filled with 3,800,000,000 yen (since it was March 8) appeared on stage. Yamashita said he would make another Kurosagi film, shooting it overseas.

The official theme song is "Taiyō no Namida" (太陽のナミダ). It is performed by NEWS, a 6-member band. Tomohisa Yamashita, who also plays the lead role, is in the band.
