The new feature is called Cinemode. Turn off your phone’s volume and launch the Cinemark app. Launch the Cinemode module and–this part is key–leave that screen up for the entire duration of the film. If you can control yourself for the duration, get rewards in the form of coupons for free or discounted concession items or (perhaps) tickets. After all, you want customers who aren’t disturbing everyone else to keep coming back.
