Says a source, "The film's plot features real sports tournaments that have a critical influence on its characters. To build authenticity and add credibility, immaculate efforts have been taken by the makers to recreate major sports events."

Ali Abbas Zafar director of 'Sultan' confirms the news and says, "You can say we have put in enough time for research of the sport. We met real life wrestlers and then incorporated that in the script; travelled extensively through Haryana and Delhi for two months and toured the akhadas (wrestling hubs) as part of our research."
