Ben Affleck in Gone Girl
A new "Gone Girl" teaser aired during last night's Emmy Awards, and man, does Ben Affleck look like he dunnit.

The TV spot reused a lot of footage from previous trailers, but it started off with a new scene of Nick Dunne (Affleck) and Amy Elliott (Rosamund Pike) first meeting.

"I'm the guy to save you," he says, super-creepily, "from all this awesomeness."

Maybe that was charming and attractive, in a cocky sort of way, but their marriage soon starts to crumble, as Amy whispers, "Man of my dreams. This man of mine may truly kill me."

So, when she disappears without a trace, who else is a target for the investigators but her dear husband?

"Gone Girl" also stars Tyler Perry, Neil Patrick Harris, Patrick Fugit, and Kim Dickens, and opens in theaters October 3.
