Kaathuvaakula Rendu Kaadhal teaser was released by Seven Screen Studio on February 11. Along with this the makers also announced the release date as April 25. 

The teaser itself hints at what audiences can expect from the film. Vijay Sethupathi (Ranjankudi Anbarasu Murugesa Boopathy Ohoondhiran) as RAMBO confesses to Kanmani (Nayanthara) and Khatija (Samantha) at the same time. He tells them both that he fell in love with them and they changed his life in a positive manner. However, he never clarifies which of them he is referring to leaving both of them and the audience in confusion.

It is equal parts funny and frustrating and there is humor in it all, and this is possibly what the film is going for and the teaser is a good start for the same. Kaathuvaakula Rendu Kaadhal is directed by Vignesh Shivan and this is his second collaboration with Vijay Sethupathi after his film Naanum Rowdy Dhaan. The music for this is composed by Anirudh Ravichander.
