The quest for popcorn is about to get impossible — literally. Regal Cinemas has unveiled its promotional popcorn bucket for Paramount Pictures’ upcoming Mission: Impossible — The Final Reckoning, and it’s banking on the recent trend of interactive buckets. Unlike past buckets, though, this one takes the interactive aspect to a new level, as the Mission: Impossibletie-in will see the user unlock it a la Tom Cruise in order to access the popcorn.
