CID stands for Criminal Investigation Department officer. The department in real world gets their marching orders from CBI - Central Bureau of Investigation, India's counterpart of the FBI. For a movie CID officer, the character has to be a master of disguises, here below are the many faces of CID Nazir.
The 60s & 70s Malayalam cinema CIDs or detectives had to have excellent cosplay skills. A CID's crime solving abilities were a distant second. Since CID Nazir is Malayali incarnate of James Bond, he is shown as an irresistible ladies man. Unlike other Malayalam movies of the time the hero does not form a lasting bond with the heroine when this movie ends.
The 1969 movie Kannur Deluxe can be considered a prequel of CID Nazir. In both movies Prem Nazir is the CID and Adoor Bhasi is his assistant CID, although P. Venu, the director of CID Nazir did direct a film called Detective 909 Keralathil (1969) prior to this, it does not have the continuity you expect in a movie series in the absence of the main character CID Nazir, which Kannur Deluxe has. P.Venu will go on to make a sequel to CID Nazir in 1972 called Taxi Car.
Other CID movies that I am familiar with from the same time period where Prem Nazir stars as the CID are Cochin Express (1967), Love in Kerala (1968), Danger Biscuit (1969), Ernakulam Junction (1971) and Lankadahanam (1972).
CID Nazir - the movie starts off with a different CID - a young and handsome Raghavan as CID Chandran. As a young and junior hero, he is expendable and is finished off before the opening credits. CID Nazir is then tasked with finding and bringing the criminal gang behind Chandran's killing to justice.

Adoor Bhasi plays the assistant CID, Bhasi. He also provides comic relief. Unlike the Malayali Bond - CID Nazir, assistant CID Bhasi has a permanent lady love in this movie, Sreelatha. Bahadur, another actor who assists Bhasi in the comic relief effort plays the caretaker and helper at the bungalow Nazir stays in. It is the same house where CID Chandran was originally murdered. Bahadur and Bhasi were like Laurel and Hardy of Malayalam of that era.

A masala potboiler Indian movie has to have a good looking heroine so that the dashing CID officer can engage in some stress-release in the form of singing, dancing and running around trees with her. A very young Jayabharathi, in her late teens is CID Nazir's girl friend for two and half hours of the movie's running time. While the girl is hopelessly in love with the CID, the upstanding CID never really expresses any deep feelings for her. She is mainly there as the subject of his songs and the movie did have some chartbuster songs thanks to this romantic track.

The villains, the semi villains, the vamp and the villain's lair showcases the usual suspects like Jose Prakash, Nellikkode Bhaskaran and Sadhana. The underground (looks like a bomb shelter) villain's lair is typical repurposed studio set that has stood many movie villains in good stead. The super villain never shows his face, as the camera shows the back of his head from behind his chair and you can see his foot soldiers facing the camera. There is an ominous globe on the villain's desk as if to say the world is not enough.

Sadhana, a Malayalam star from the 60s and 70s who specialized in vamp and cabaret dancer roles is the femme fatale. She gets a pretty meaty role trying to mislead and murder the ladies' man CID. She also gets a cabaret dance number and song and in the end she switches side, thus redeeming herself and reuniting with her ex-boyfriend. I tried looking up Sadhana and found that the lady died penniless - the same fate met by many supporting actors in Malayalam film industry.

K.P. Ummer as Das |
K. P. Ummer - another mainstay actor of 1960s-70s Malayalam movies makes his appearance as Das, Miss. Lovely's boyfriend and CID's secretary. He makes his entrance one day at mid-night at CID's bungalow, looking for a job and CID offers him the job of his secretary. Why at that hour is a question we should not ask, it could be that the investigative types could only be cornered at their abodes at mid night and therefore it was the best time to ask for a job. Ummer was usually the second hero, if the movie had space for more than one or on rare occasions, he donned negative characters as well. Speaking of not-so-innocent characaters, Nellikkodu Bhaskaran and Jose Prakash play a couple of dapper characters who are sus.
