Sonakshi Sinha with her father Shatrughan Sinha.
Sonakshi also said that her father will be very proud of the "hard work" she has put into the promotion of her film.
"The promotions are not getting affected in any way, in fact, they are going on very smoothly. My dad will be proud of our good work. He is fine, that is all I can say," she said.
Directed by Shirish Kunder, Joker also stars Akshay Kumar.
After being a part of Rs. 100 crore blockbusters like Dabangg and Rowdy Rathore, the actress said she chose Joker because of the uniqueness of the script.
"Our film's uniqueness is our USP. I like sci-fi books and movies. I found the script very interesting and such a genre has not been attempted before. It was a very different experience for me," she said.
Praising her team, the actress said that Joker was a culmination of the collective efforts put in by the director and the team.
"This is the collective effort of so many talented people. The movie is all thanks to their hardwork," she said.
