"I am very fortunate and blessed that I am working with him. Film is releasing next year and this is our final schedule so all of us are trying to do our best job. I am still getting used to it (working with Rajinikanth)," said Huma on the sidelines of the special shoot of Miss Diva 2017 along with Lara Dutta on Friday.
"'Kaala' is a very beautiful script. When I heard the script, I was like, I have to be part of this film and of course, working with Rajinikanth sir is a dream come true. In life, you get very few opportunities that you should grab with both your hands," she added.
Talking about her work hours and busy schedule, the "Dobaara" actress said that she is "going to have 48 hour work day" for the film.
"I am all charged having lots of black coffee. I am very excited to be on 'Kaala's set. It's a final schedule and fingers crossed. It's a very special film for me," said Huma.
"Kaala" also features Nana Patekar, Jackie Shroff, Pankaj Tripathi, Anjali Patil, Sayaji Shinde and Sakshi Agarwal in key roles.
Directed by Pa. Ranjith, the film has been produced by Rajinikanth's son-in-law and actor Dhanush under his production banner Wunderbar Films.
"Kaala" is scheduled to release on April 14 next year.
