"Nearly 25 VFX shots are yet to be completed. It was supposed to be completed by March 27, but it got delayed for various reasons. Now the film will not release on April 10, and instead the makers are planning to release on April 24 or May 1," a source from the film's unit told IANS.
VFX supervisor Madhusudanan, who has earlier worked on Haasan's films such as "Alavandhan" and "Thenali", is busy overseeing the pending work.
"Kamal sir has requested Madhu not to rush. He said he doesn't mind waiting for two more weeks but doesn't want to compromise on the output," the source said.
Directed by Ramesh Aravind, "Uttama Villain" is the story of a theatre artist in the 8th century and a modern day superstar.
The film also features K. Balachander, K. Vishwanath, Pooja Kumar, Andrea Jeremiah, Jayaram, Urvashi and M.S. Bhaskar in important roles.
