Looks like Prakashraj will replace Salim Ghouse as the main baddie in Karthi's Saguni. The story goes like this; Recently Karthi's dad Sivakumar and brother Suriya watched Saguni at a special screening in Chennai. Apparently the duo was not happy with Salim's performance in the film and then they decided to re-shoot the portion with Prakashraj. The film is directed by debutant Sankar Dayal (a former associate to Ezhil and S.D. Saba).

From the trailer it is clear that Karthi will play the role of Kamal, a street-smart rookie who, through his crooked yet intelligent moves, becomes the Chief Minister of a state. After Siruthai, Karthi is teaming up with Santhanam again in Saguni and their chemistry is one of the major highlights of the film. Kannada actress Pranitha plays the leading lady. The film also has Santhanam, Radikaa Sarathkumar, Kota Srinivasa Rao, Nasser, Roja and glam queen Mumtaz in prominent roles.
