The make up for the role of Kambar, in the movie Ambikapathi starring MKT, was deliberately done to resemble a national leader.Who?

Rabindranath Tagore.

The director ( I think it was Y.V.Rao) was a fan of Tagore. So he insisted that kambar- played by Perugalathur Sama - was given a long hair and flowing beard.The fact that nobody knows how Kambar looked like did help.
