Well, not having seen the movie but I’ll correct a two-year old posting…
A toilet would make a fine drain for a room filling with water, provided the drain pipe lead somewhere where there wasn’t water and the fill rate didn’t exceed the drain rate. The water would fill the room to the level of the bowl, then flow evenly down.
Prove it? Pour a bucket of water into a toilet. It goes nicely away without pushing the handle.
Well, just to wander far off topic for a moment… The Atari of today is really a large French video games publisher called Infogrames, which purchased the Atari name as a part of its Hasbro acquisition in 2000. Nothing of the original company is left, save the name and logo. I gnash my teeth when I see that logo in the stores, not that it does any good.
By “small detail of the storyline,” I was being sarcastic: referring to the storyline as a whole as a detail to which the filmmakers should have devoted more time. The overall plot couldn’t have been more generic if it came in a white can labeled in big black letters “STORY.”
