A cinema app, which is available on Apple, Android and Windows phones, tells you the best times to dash to the loo without missing any key scenes.
The staff behind RunPee make a note of any three-to-five minute slots when the film starts to drag a bit, the Daily Mail reported.
Helpfully, the app then gives movie buffs a synopsis of what happened while they were away in the loo.
Movies up to 90 minutes get one break, but for longer films the app offers two or three possible slots. (ANI)
