10 Rules For Surviving Action Movies
4. Never Lock The Bad Guy In A Clear Prison
Not only does locking a bad guy in a clear prison give them the chance to have a heart-to-heart with one or more of the main characters without those pesky bars ruining the shot, it also gives a clear sign that a theatrically-planned escape is imminent, one that always ends with collateral damage as several faceless subordinates are taken out along the way.
As we've seen in X-Men 2, The Avengers, Star Trek Into Darkness and Skyfall, the villain usually has the chance to give a lengthy monologue that explains their reasoning and justification for wanting to kill everyone before it turns out... they wanted to be captured all along!
While nobody important to the plot usually winds up dead from the subsequent jailbreak, spare a thought for those unfortunate souls who don't even get a name in the credits that wind up on the receiving end of the inevitable escape.
