The Call

Leaving the bunker, Jordan tries to call 911 on her cell phone.

The next shot shows the phone's home screen rather than the phone screen.

When Jordan stumbles upon the trapdoor access to the underground bunker, it is covered with leaves and debris.

But Michael is already inside, so the debris would have have fallen away when he opened the trap door.

When the call center supervisor approaches Jordan's desk to tell her they're still working on tracking Casey's phone, her headset disappears from her right ear between shots.
