No doubt you've been at a cinema where somebody's on their phone, checking a text message or - as we saw one time - literally having a full-blown conversation about who left a door unlocked and a dog getting out.
Most cinemas have a public service announcement before reminding people to turn off their phones, however Alamo Drafthouse always does it one step further than most. Previously, they had Richard Linklater explain to the audience how to murder someone with a pencil if they saw someone texting.
This time around, it's Jackson Robert Scott - who played Georgie in the new adaptation of It - terrifying people into not texting.
Take a look.
