He feels too much work means not doing justice to any of his films.
"I want to deliver the best. I want to devote my time completely to one film. Right now I don't feel I am doing justice to any film and I gave it a lot of thought. So I have decided to do only one film and live up to the expectations people have from me," the 30-year-old said here Friday at the Filmfare awards South press conference.
Right now Dhanush has a lot of Tamil films in hand but he plans to wrap up everything by the end of this year and start 2015 afresh.
"I will do one each (in Hindi and Tamil), that is the only practical thing that can be done. Right now I am doing one Hindi film and wrapping up a couple of Tamil films and I am starting two more Tamil films this year," Dhanush said.
"By December or January I will be done with all these films and then I will start afresh. I want to really reduce the number of films and do very limited films," he added.
Dhanush is currently shooting for R.Balki's film "Shamitabh" which also stars megastar Amitabh Bachchan.
