Tom Cruise thrills in 'Mission: Impossible - Dead Reckoning Part One' trailer

Thrill-seeking movie fans finally got the official trailer for "Mission: Impossible - Dead Reckoning Part One" on Wednesday, and it's intense.

"Our lives are the sum of our choices, and we cannot escape the past," warns Henry Czerny's Eugene Kittridge -- the thorn in the side of Tom Cruise's superspy Ethan Hunt from the very first film. "Ethan, this mission of yours is going to cost you dearly."

Series newcomer Hayley Atwell, who plays Grace, says in voiceover, "The world is changing. Truth is vanishing. War is coming," amid footage of a submarine destroying another with a torpedo.

The trailer also gives a closer look at the film's big bad, played by Esai Morales. "It's been a long time, friend," he tells Hunt. "You have no idea the power I represent. It knows your story, and how it ends."

"Guardians of the Galaxy" vet Pom Klementieff, her face decorated in harlequin makeup, plays a deadly assassin.

Morales' as-yet-unrevealed character threatens Hunt's team -- made up of returning players Simon Pegg, Ving Rhames and Rebecca Ferguson -- which is obviously a mistake. "If anything happens to them, there's no place that I won't go to kill you," Hunt seethes.

"None of our lives can matter more than this mission," Rhames' character Luther tells Hunt.

"I do not accept that," Hunt responds flatly.

Interspersed with the dialog and hints of the mysterious plot are intense action set-pieces, from car chases to gunfights to horseback pursuits, and a knife fight on top of a speeding train.

Of course, there's the feat Cruise has called the most dangerous he's ever done: driving a speeding motorcycle off a cliff, launching him into the air for a skydiving stunt.

"Mission: Impossible - Dead Reckoning Part One" explodes into theaters July 12.
