Makers and star cast of 'One Day: Justice Delivered' attended the trailer launch event in Mumbai. Lead actors Anupam Kher and Esha Gupta shared their experience, while talking to mediapersons. Esha Gupta said, "I was more excited than nervous on my first day at the sets because being an alumni of 'Actor Prepares', it was a proud moment for me to share the screen space with my guru." Anupam also shared his style of work. He said, "Everyday I go to work, I tell myself that I don't know anything about acting. We are all under the weight of our knowledge and as long as we stay under its weight, we won't be able to learn anything new. So, I always think that I don't know anything before going to sets. And, it does make difference. When you learn from everyone else, it's a great thing. " Helmed by Ashok K Nanda, the movie will release on June 14.
