It is almost twenty years since Revathy took up to acting.
She was known as Manvasanai girl in Tamil. It was her first film.
Her second film Kattathe Kilikkodu established her in Malayalam.
She earned critics opinion in Kakkothikkavile Appoopppan Thadikal. She made people laugh in Kilukkam. Her performance was unparalleled in Devasuram.

She recently played a role of mother to Mohanlal! In Ravanaprabhu. Like Suhasini, Revathy has no complex image. In fact she has started accepting old age roles on her own will. And she has enough roles also. She does not demand her role be that of the leading lady, young and beautiful. Revathy is more realistic than the male super stars. She says that she can become the leading lady if the character is of her age and looks. But no more romantic roles.

She has completed two films recently. Nandanam by Ranjith and Gramaphone by Kamal. In Gramophone she has played the role of an old Jew woman of Cochin, Sara. A role of a lifetime. Sara shuts up herself in an old colonial house she gets out to the streets where once she breathed the fresh and free air of youth and love. A cool gush of memories. The role itself lends a lot of emotional moments to express and Revathy had exploited them in the film. She is presently doing a role in Kaiyethum Doorathu by Fazil.

Her first directorial venture Mitr a bilingual and all women crew film gave her immense satisfaction. She is planning a second feature film now. She said she had read a couple of scripts and will shortly decide the one to shoot. "This will be a commercial one'. The reason 'There should be a change always"
