If you loved Busty Girlfriend, try The Tower
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What The Tower is
You arrive for drinks in a Seoul luxury skyscraper where the champagne fizz hits colder than the December sky, then the lights flicker and the fire alarm screams. Exits seal themselves as the building tilts and smoke rises between floors. In the forty-ninth minute the structure starts to fold like paper.
