Versatile actor Shreyas Talpade has been roped in as the second lead in Shirish Kunder's "Joker" and will be seen as Akshay Kumar's brother in the 3-D movie.

"Shreyas Talpade has been cast as the second male lead in 'Joker'. He plays Akshay Kumar's brother in the film, " Kunder posted on his Facebook and Twitter page Monday.

While Sonakshi Sinha has been zeroed in on as the female lead opposite Akshay in the film, the second female lead is yet to be decided. Kunder is taking public opinion for the same through his social networking accounts.

"Who should be the heroine opposite Shreyas Talpade in 'Joker'?" he posted soon after announcing Shreyas' presence in the film.

He has been taking public opinion for his upcoming project through social networking sites. He has been posting questions like "Who should be the lyricist for 'Joker'?" and "Who should be the music director for 'Joker'?"

The film editor-turned-director, husband of choreographer-director Farah Khan, had earlier shared a few details of his project through the social networking sites.

"Joker is not a superhero film. At one point it used to be. But what we are making now is a completely new script, with the same title. Joker has nothing to do with Batman's or Raj Kapoor's Joker. And Yup...Joker is a 3D film (sic), " Kunder had posted.

The film is being jointly produced by Kunder and Farah's Three's Company and Akshay Kumar's Hari Om Entertainment Company. They worked together on "Tees Maar Khan" recently.
