Salah satu persoalan yang menjadi pedebatan berbagai kalangan adalah ketimpangan gender. Film Dangal yang rilis pada 23 Desember 2016 ini menggambarkan ketimpangan gender yang diterima oleh Mahavir dan kedua anak perempuannya karena bergulat. Film Bollywood ini berbeda dengan film Bollywood lainnya, pasalnya film-film Bollywood lain yang diketahui masyarakat mengedepankan cerita cinta, nyanyian dan tarian, sedangkan film Dangal menampilkan cerita yang menarik, dan penuh dengan makna didalamnya. Berdasarkan latar belakang di atas, pertanyaan dalam penelitian ini adalah bagaimana makna denotasi ketidakadilan gender yang terkandung dalam film Dangal? Bagaimana makna konotasi ketidakadilan gender yang terkandung dalam film Dangal? Bagaimana makna mitos ketidakadilan gender yang terkandung dalam film Dangal? Penelitian ini menggunakan paradigma kontruktivisme dimana bahasa tidak

    When the Best of Bollywood Directors (Anurag Kashyap, Imtiaz Ali, Vishal Bhardwaj) Want to Cast for Their New Films, Their Roads Lead to One Man — Mukesh Chhabra

    UP CLOSE The New Godfather When the best of Bollywood directors (Anurag Kashyap, Imtiaz Ali, Vishal Bhardwaj) want to cast for their new films, their roads lead to one man — Mukesh Chhabra. By Ekta Mohta Photograph by Rohit Gupta wall in Mukesh Chhabra’s studio, in Aram Nagar, Mumbai, is covered with messages from second- rung stars of the Hindi film industry — Huma Qureshi, Sushant Singh Rajput, Rajkummar Rao, Aditi Rao Hydari, Jimmy Shergill, Swara Bhaskar. Of these, one message, by Vineet Kumar Singh, who played Danish Khan in Gangs of Wasseypur, stands out: “God selected you to find those who are talented.” When we meet, the 35-year-old Chhabra is wearing a white T-shirt, tinted spectacles and a five o’clock shadow. “My face has become like this because I’m auditioning so much and rejecting so many people. I’ve become a mean person,” he says, softly and sweetly, in north Indian-accented English. His studio is like anA immigration centre, where 43 employees guide hopefuls arriving every minute. “Three hundred people come to my studio every day. Out of that, one person will know how to act. Without knowing their craft, they want a role. In India, everyone wants to be an actor — reporters, RJs, cops, my doctor. I’m like, what is happening in this country?” In 2015 alone, Chhabra has cast films such as Badlapur, Bombay Velvet, Bajrangi Bhaijaan, Masaan, Shaandaar, Tamasha and Aligarh; his roll call of earlier films include Shahid, Luv Shuv Tey Chicken Khurana, Kai Po Che, Chennai Express, Hasee Toh Phasee, Rockstar, Bhoothnath Returns, Highway, Haider, Ugly, PK and many others.
