"How long can you tread water?"

The upcoming movie Noah seems to have more magic in it than one might have expected.  Someone plunges a wooden rod into the ground, unleashing a spreading ring of fire; stuff like that.  Some miraculous stuff is part of the story, of course; we see snakes and birds and animals streaming toward the ark.  And falling fireballs and gigantic geysers, which I think were not in the original story, but my knowledge of it is spotty.

Modern effects technology could do something towards explaining some of the long-standing mysteries.  All of the animals going into the ark could be seen to shrink as they enter, so there would be space for all of them.  They wouldn't even have to explain it, just show it.  Emma Watson's role in the movie might lend credence to the effect.

Really, there should be a Doctor Who episode which shows him going back to help Noah.  He could either apply some transdimensional technology, or just... well, there's lots of room inside the TARDIS.
