There are plenty of things we scream out at the characters caught in bad situations in the movies -- "Don't answer the door!", "Grab the knife and run!" -- but of course, they never listen. The former warning would come in handy to Ethan Hawke's son in the new thriller "The Purge,"
in which he lets a man on the run enter their locked-down home during Purge day, when all crime is legal.
When it comes to home invasion movies there are plenty of tips we can learn for how to survive one should we ever get stuck in a scary movie ourselves. Whether it's fighting back, locking the door, or using clever tricks to deter the bad guys, this list of Do's and Don't's would save any (we hope) movie character in distress.
