You can watch the full ad belowUS telco Sprint has created an interactive cinema ad which reminds moviegoers to turn off their mobile. The ad, created by integrated brand agency Digitas and ad agency Leo Burnett, directs the audience to text “DREAM” to a shortcode before putting their phone to sleep for the duration of the film.

When the phone is turned back on, users will find a text prompt asking them to opt-in via Facebook. They are then shown a personalised 15-second video clip, based on their Facebook activity and photos, showing what their phone has been dreaming about while it was off.

“Many have created on-screen cinema spots before, but no one has tied it to a phone experience,” said Kevin Drew Davis, EVP, Executive Creative Director, Digitas. “We’ve taken cinema from the silver screen to your mobile phone, all while activating a social community that can spread the word outside the theater.”

The ad, which will be shown across nearly 19,000 screens in 1,500 NCM-affiliated cinemas, can watched below.
