Actor Tom Hanks says humans are selfish and follow their own will.
"Do you believe that there are organisations that are controlling the destiny of mankind? I don't think there's anybody who's hatching plots to get us, beyond the press of course," Hanks said at an event, organised by Sony Pictures Entertainment in Singapore.
After giving a visual translation to author Dan Brown's "The Da Vinci Code" and "Angels & Demons", director Ron Howard has infused life to his popular book "Inferno".
In the film, based on the 2013 novel of the same name, Hanks will be seen reprising the role of Robert Langdon, a professor of symbology at Harvard University. Indian actor Irrfan Khan is playing Harry "The Provost" Sims, head of The Consortium, in the movie.
The trilogy has strong religious themes, and also shows that it is the human power that decides the fate of the earth with a shadowy organisation controlling the destiny of mankind.
Talking about the same, Hanks said: "I think at the end of the day, in my mind, the concept of conspiracy theories falls apart because nothing trumps human behaviour and humans are selfish and self-motivated and will follow their own will."
He added: "I think by and large any organisation cannot stay secret because people like to talk and they can't stay efficient because people are lazy and they don't want to work that hard."
The film will present a trail of clues tied to the great Dante himself. When Langdon wakes up in an Italian hospital with amnesia, he teams up with Sienna Brooks (played by Felicity Jones), a doctor he hopes will help him recover his memories. They race across Europe and against the clock to foil a deadly global plot, and Irrfan joins their mission to save the world.
The film is releasing in India on October 14.
