Walter White Looks Scared In New 'Breaking Bad' Teaser (VIDEO)

In a new, tantalizing, 10-second "Breaking Bad" teaser, Walter White looks downright scared.

Bryan Cranston's chemistry teacher-turned-meth kingpin stands (Tony Soprano-style) at the edge of his driveway, wearing his robe and slippers, with a look of horror and panic.

But what is that he's holding in his hands? The camera's zoom-out makes it impossible to determine for sure, but several YouTube commenters offered the theory that he's clutching a police GPS tracker he's just discovered under his car.

Another option is that Walter is holding the Gale-signed copy of Walt Whitman's "Leaves of Grass" that his brother-in-law, DEA Agent Hank Shrader, discovered while on the toilet.

Either way, Walter looks like he just realized the walls are closing in.

This is the third "Breaking Bad" teaser to hit the internet in the last week. The other two showed Jesse looking strung-out, and an enraged Hank after learning about Walter's hidden identity.

"Breaking Bad" returns for its final eight episodes on August 11 at 9 p.m. ET on AMC.
