The mixing has started and going on in full swing for Manirathnam’s “OK Kanmani” starring Dulquer Salman and Nithya Menon eyeing an April release. Back in 2000 the Manirathnam-A R Rahman-P C Sriram combination made box office history with “Alaipayuthey,” and 15 years later their coming together has fans waiting anxiously for a repeat. Prakash Raj is playing an important role after a gap and one more big name who is attached to the project recently is Telugu actor Nani of “Naan E” fame. Since “OK Kanmani” is a trilingual in Tamil, Malayalam and Telugu, Nani is going to provide the voice for hero Dulquer Salman in the Telugu version of this romantic film with the Manirathnam touch.
