'Inferno' Teaser Trailer: The End of Human Race Is in Robert Langdon's Hands

'Would you pull the switch if it meant saving humanity?' reads the tagline of the first sneak-peek video released for the third installment of Dan Brown's Robert Langdon books.

AceShowbiz - Columbia Pictures has dropped the first teaser for the "Inferno" movie ahead of the full trailer release. The 30-second video hints that Tom Hanks' Robert Langdon will face a major dilemma as he has the option to save humanity by sacrificing half of them or let the human race be extinct.

"There's a switch," says Ben Foster, who plays the film's villain Bertrand Zobrist, in voiceover. "If you throw it, half the people on Earth with die. But if you don't, in 100 years the human race will be extinct."

In the third installment of Dan Brown's Robert Langdon books, Langdon awakens in an Italian hospital with amnesia. He teams up with Sienna Brooks (Felicity Jones), the doctor he hopes will help him recover his memories and prevent a madman from releasing a global plague connected to Dante's Inferno.

Ron Howard, who returns as director for the upcoming movie, tells EW, "Langdon is thrust into this crisis without knowing why or how he got there or what his role is. It gave Tom a lot to play with. And it allowed me to stage this as a modern psychological thriller."

Also featuring Irrfan Khan as Harry Sims/The Provost, Omar Sy as Christoph Bruder, and Sidse Babett Knudsen as Dr. Elizabeth Sinskey (the head of the World Health Organization), "Inferno" is slated to open in U.S. theaters on October 28.
