Here's what we can gleam from the new trailer for "Gone Girl," the upcoming big-screen take on Gillian Flynn's best-selling novel:

1. Yup, Ben Affleck looks like he's totally got that cad/potential murderer thing down.

2. Neil Patrick Harris is creepy like you would never imagine.

3. Tyler Perry -- a surprise casting -- looks like he's just about perfect as the high-octane defense lawyer.

All told, the second trailer for "Gone Girl," released on Monday, will likely do little to dampen the buzz that's building for the David Fincher film starring Rosamund Pike as a famous wife who goes missing and Affleck as the husband who is fingered for the disappearance.

The film, part mystery, part cat-and-mouse thriller, is due in theaters Oct. 3.
