returns as Robert Langdon in "Inferno," the latest Dan Brown novel to be adapted for the big screen. The action-packed first trailer, co-starring , was just released, and it immediately presents an impossible Sophie's Choice:

"There's a switch. If you throw it, half the people on Earth will die. But if you don't, in 100 years, the human race will be extinct."

Hmmm. Maybe aim for a third option there? The story thrusts Langdon -- "humanity's final hope" -- into the world of Dante's hell.

Here's the official synopsis:

"Academy Award winner Ron Howard returns to direct the latest bestseller in Dan Brown's (Da Vinci Code) billion-dollar Robert Langdon series, Inferno, which finds the famous symbologist (again played by Tom Hanks) on 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 (Felicity Jones), a doctor he hopes will help him recover his memories. Together, they race across Europe and against the clock to foil a deadly global plot."
