It is Kamal, not Crazy Mohan, who has penned the dialogues for Uttama Villain

The team of Uttama Villain recently wrapped up the film���s shoot in Chennai and the post-production work is going on in full swing. While it was believed until now that Crazy Mohan had written the dilaogues, the film���s director Ramesh Aravind���s informs us that the film���s dialogues were actually written by Kamal Haasan.
Ramesh says, ���This time, Kamalji wrote the dialogues as there���s another ���huge spectacle��� angle apart from the humour in the script.Since he���s written the script, he was keen on writing the dialogues as well.��� However, the actor-filmmaker adds that Crazy Mohan���s inputs are part of the film. ���Crazy Mohan is a long-standing friend. We always take his views and inputs on the storyline,��� adds Ramesh.
The film that stars Kamal in a dual role has Pooja Kumar, Andrea, Parvathy Menon and Jayaram in pivotal roles.
