Boyhood is currently in cinemas at the moment and we absolutely loved it. So much so, we gave it five stars. However, we'd also like to award its director, Richard Linklater, another star for this great little instructional video.

The Dazed & Confused director shows you how to kill someone using a drink straw if you happen to find someone texting or talking during a film. Because, let's face it, those people are the worst.

 

Don't Talk - Richard Linklater from Alamo Drafthouse on Vimeo.

 

The video itself was commissioned by the Alamo Drafthouse Cinema to run before its screenings of Boyhood. To be honest, this should shown in all cinemas. All the time. UNTIL PEOPLE TURN THEIR PHONES OFF.
