Radhika Sarath Kumar,who has earlier been active in films and who now is busy producing and acting in tele-serials,is all set to make a comeback in films. She plays a key role in the Karthi starrer Saguni. Saguni,as the title suggests,is about a person who uses people and situations for his gains in a very shrewd manner. The film is directed by debutant Shankar Dayal and is produced under the banner of Dream Warrior Pictures. Music is by GV Prakash Kumar while PG Muthiah is in charge of the cinematography. Sources at Radaan,Radhikas production company,say that she is playing a key role in the film. She had been away from films only because of her other engagements,especially relating to the small screen. Radhika is the wife of actor Sarath Kumar. Saguni is getting ready for a Diwali release.
