'Paranormal Activity' 4 trailer

You want to see something really scary?

The trailer for Paranormal Activity 4 has arrived, and as you might expect, it's more of the same: shaky camera, creepy figure in the background, and a guarantee that something seriously disturbing is going to happen when you least expect it.

It's no surprise that a fourth film is happening. After the incredible debut of the original dirt-cheap found-footage thriller, the second and third Paranormal movies combined to earn $383 million at the global box office. The fourth movie will be released on Oct. 19, just in time for Halloween.

Check out the trailer for the fourth installment below:
