The theatre personalities of Kerala initially staged classical Sanskrit plays, but not entirely Sanskrit theatre in the strict sense because the enactment included elaborate oral elucidation in Malayalam. The form of art - Kuttipalam is now performed by the theatre personalities of Kerala within the premises of the major temples in central Kerala. However, other native traditions of Malayalam theatre may be even older than Kutiyattam.

The influence of these theatre personalities of Kerala on the masses grew so strong that even generally realistic drama began to be produced with the addition of songs. A literary development brought about a far-reaching change amidst the audiences. C. V. Raman Pillai, E. V. Krishna Pillai, P. J. Antony, C. N. Srikanthan Nair, K. T. Mohamed, N. P.
