Movie Operation Bangkok / เพชรตัดเพชร was released in year 1966 and lasts 1h50mn. It is a HK Thai co production managed by three film directors including Wichit Khunawut. Mitr Chaibancha meets Yot (Luechai Natnat). An exchange of suitcases happens over a bridge. Adinan Singhiran is Yot’s acolyte. Yot betrays Mitr and tries to keep the two suitcases. Shooting happens and Yot flees. Choomporn Theppitak is part of a gang led by Kecha Plianvithee. Yot belongs to the same gang also. Luechai arrives in Hong Kong. He meets Adul Dulyarat on a boat to exchange drugs against money. The drug is fake and he steals the money by punching Adul. He flees to Bangkok and escapes to Choomporn, who tries to shoot him with a long range rifle. Yot has betrayed (ทรยศ) Kecha. Yot meets singer Pai Lu (Hong Kong actress Regina Pai Ping) in the plane and sympathizes. Mitr disguises himself as Chat, a tough ruffian, to infiltrate Kecha’s gang. Chadaporn Wachirapranee is Chat’s old wife so he punches Sompol Kongsuwan to show he is back. Chao Klaewklong introduces Chat to Kecha. Kecha is looking for a new right-hand man (แขนขวาคนใหม่) as Yot betrayed him. Kecha wishes Chat to get rid of Yot. Ratsamee (Petchara Chaowarat) loves Yot but Yot also loves Pai Lu, who is in fact an undercover policewoman from Hong Kong. Ratsamee warns Yot that Adul is around looking for him. Pai Lu and Ratsamee escape from Adul but get arrested by policeman Lor Tok, who ignore they are from Interpol Police (ตำรวจสากล). A painting called เพชรตัดเพชร is purchased by Wilaiwan Watthanaphanit bidding against Kecha. Miss Boran (Kaenjai Meenakanit) is the sexy painter. Adul wishes to buy the jewel hidden in the painting but this one is now always worn by Miss Boran. The jewel contains a password (รหัด). Choomporn kills Miss Boran to get the jewel but Yot and his team steal it from him also. Pai Lu is surnamed HK 16. Mitr is surnamed BKK 38 (ตำรวจไทยเจ้าชู้อย่างนี้ทุกคนหรือค่ะ?). Mitr helps Pai Lu chased by two ruffians including Choomporn. Chat brings Pai Lu himself to Kecha. Understanding that she is an enemy (ศัตรู), she is condemned to be shot by Choomporn but Chat succeeds to charge the gun with blank bullets. Yot falls in a trap prepared by Adul to steal the diamond but it fails and Adul dies. Yot wishes to make peace with Kecha. Kecha wants only one right-arm man so both Chat and Yot have to fight against each other. Pai Lu and Petchara ask them to stop fighting. They are all captured by Kecha. Part of the movie is then lost here. Wilaiwan shots Ratsamee. Hopefully Pai Lu shots Wilaiwan and can help Ratsamee on time. Thai police attack the ruffians. All are killed or captured but Kecha succeeds to flee. Kecha refuses to surrender to the Thai police and prefers to explode his boat. The movie ends up on a sad note as Pai Lu has to leave Chat to go back back to Hong Kong, Ratsamee is separated from Yot as he has to go to jail. This movie is still available in Hong Kong under title 諜海蛟龍 and was shown on cable TV. The famous song of this movie is ดวงใจ by singer สวลี ผกาพันธุ์. This movie is one of the best confrontations between Thai superstars Mitr Chaibancha and Luechai Natnat. As it is a HK Thai co production, it is interesting to find that the Chinese version poster features Chinese actress Regina Pai Ping’s head in big size. Mitr Chaibancha and Petchara Chaowarat are displayed in small size. But the Thai poster displays more prominently Mitr Chaibancha and Petchara Chaowarat. In the Chinese synopsis, Mitr Chaibancha is written as mi-tsai- wan-chai (Thai detective No 78) and called as Ah Tsai in the movie. Regina Pai Ping (Hong Kong agent No 113) is called as Pai Lu in the movie. Petchara Chaowarat is written as Pi-chai-la and called as Sha Mei in the movie. The movie was so famous that it was released once in year 1966 and then reshown again in year 1975. The original version lasts 2h20mn but the 1975 version was reduced to less than 2 hours as both movies เพชรตัดเพชร and คนเหนือคน were shown together. The DVD released by company Pantamit is based on the 1975 version. It took five years for company Pantamit to convince the film owner to lend it in order to make a digital copy. Another film copy remains in the Thai Film archives.
