The official trailer of Shirish Kunder’s ‘Joker’ will be released with Saif Ali Khan’s ‘Cocktail’ this Friday. The trailer has apparently been given a ‘U’ certificate. Shirish’s second film as a director is apparently a science fiction movie that stars Akshay Kumar, Sonakshi Sinha, Shreyas Talpade, Minisha Lamba and a host of other actors. Referring to the sci-fi tilt of the movie, Shirish’s wife, choreographer and director Farah Khan recently tweeted, “There’s an Alien in my house!! 2 days for ‘Joker’ trailer and the aliens have started visiting!” Chitrangda Singh has performed an item number for the film, which was recently leaked online causing the filmmakers much anguish.
