The movie industry sees the illegal recording of movies as one of the biggest piracy threats and for years has gone to extremes to stop it.
It started well over a decade ago when visitors began sneaking handheld camcorders into theaters. These big clunkers were easy to spot, but as time passed the recording devices became smaller and easier to hide.
While recording a movie for strictly personal use is not illegal in UK cinemas (despite industry efforts to have the law changed), theaters continue to outlaw the use of recording devices. Most recently, Google Glass was banned, and phones and tablets need to be switched off as well.
In a code of conduct the movie industry and cinemas have agreed that employees will take immediate action when they spot someone with a recording device, but some cinema staff take these obligations way too far.
At a Cineworld cinema in Brighton Marina, UK, employees dialed the national 999 emergency number after they spotted a group of 12-year-old girls with iPhones and iPads at a showing of The Hunger Games.
The girls, accused of recording parts of the movie, were hauled outside where two police cars rushed towards the scene with flashing lights.
