Even as busy gearing up for his marriage (July 3) at one side, Karthi Sivakumar is on a signing spree on the other. The actor, who is currently busy shooting for 'Saguni', has given consent to be part of a film directed by Suraj.

If sources are to be believed, the full-length commercial entertainer, which will be quite typical to Suraj's style, will have Anushka as the leading lady. "The shooting will start once Karthi completes his portions in Saguni."

"Karthi and Anushka were about to share the screen space in Siruthai itself, but it did not take place as the actress found it difficult to allot dates at that time," sources say. Interestingly, Siruthai's original version 'Vikramarkudu' had Anushka as heroine.

Meanwhile, talking about marriage, Karthi said in a recent interview, "I don't think marriage will change much. More than change, marriage will make me a bit more responsible. I think when you're a bachelor, taking risks doesn't matter much but after marriage, I think I would be taking less risks."
