There's a big misconception that toilets flush in one direction in the northern hemisphere and a different direction in the southern hemisphere. The misconception describes the Coriolis Effect as the cause. The Coriolis Effect is a real thing and determines which direction storm systems rotate, but it doesn't work on small scales...such as a toilet. Toilets flush in a certain direction based on toilet design. In other words, toilets can flush counter clockwise AND clockwise in the northern hemisphere. The same is true for the southern hemisphere.
Escape Plan was a decent movie if you're looking for some hard core action with no romance, but in terms of science, nope.
