Howling:5 things to look for: Cracks

Please see the original thread Forum:5 Things to look for in Series 5 and the summary thread Forum:5 things to look for: Overall.

The evidence for this one is pretty blatant, and there's already an article on The Cracks, but just for completeness, here's a thread:

 * The Eleventh Hour: The whole episode is about Prisoner Zero coming through a crack on Amy's wall. There's also a crack on a TARDIS monitor readout.
 * The Beast Below: The camera zooms in on a crack on the hull of Starship UK after the TARDIS leaves.
 * Victory of the Daleks: The camera zooms in on a crack in the wall, in the back area of the Cabinet War Room, not visible when the TARDIS arrives, but visible when it leaves.
 * The Time of Angels/Flesh and Stone: There doesn't seem to be any crack in TToA (except in the "scenes from next time"), but it's visible in FaS, and remarked on as "extremely, very not good" by the Doctor, and a Digital Spy teaser reveals that we will find out what the cracks are and what they want.
 * Vampires of Venice: In the sky
 * Amy's Choice: Unknown
