: The most significant driver of this rumor is a case of mistaken identity. In the early 2010s, reports surfaced of an actress named "Sukanya" being arrested in Chennai on charges of prostitution. The reality, which was later clarified by several media outlets, is that the woman arrested was a Bengali television actress who shared the same name. She was not the celebrated South Indian film star. This incident created a media firestorm, and the name "Sukanya" became erroneously linked to a major scandal. The "blue film" part of the search term is likely a sensationalistic extension of this prostitution scandal, with internet users erroneously assuming the existence of an adult video or "blue film" starring the wrong actress. This confusion was so significant that news reports from 2016 state, "Here is a news article that clarifies the rumor surrounding actress Sukanya in a prostitution case and states that the actress arrested is a different Sukanya, a Bengali actress, and not the popular South Indian actress".
