K.Bala Chander modelled himself on Director Sridhar in some crucial ways: both came from theatre.Neither worked as an asst to any director. Sridhar had the knack of bringing out the best in Nagesh,the comedian. But KB had the guts to cast him as a hero in 5 films (1964-68).Nagesh was lean,short and his face was pock_marked.His films with KB reflected ALL the insecurities of a typical middle-class Tamilian with ruthless self_analysis and mininimum melodrama.He could have become a second Sivaji.But market forces threatened the duo of KB_Nagesh.They were separated.Tamils were unwilling to bear too much reality.An ugly short fellow was not allowed to keep on succeding. Only MGR could succeed on screen. Nagesh had to remain a comedian except for the occasional film of Sivaji who allowed him to blaze: see "Savale samaali"," Thillana Mohanambal" and "Gowravam". KB had to rely on kinky sex/libido to keep him afloat in the commercial world. Something similar happened to the great Raj Kapoor: once Nargis stopped acting with him,his stories were dominated by mammaries.Strong story became increasingly invisible. KB_Nagesh duo could have delivered SOME STUFF similar to Ray_Sowmitra Chatterjee duo.KB took vengeance on Tamils. Server is a classic and looks as if KB built on Nagesh's diary.
