Interdimensional tales

The tales are not particularly "creepy", but they are new and somewhat interesting, if one has an interest in science fiction ideas for stories.

It does make me think that the genre of interdimensional travel has been little explored in science fiction movies.  (It has had a much better run in books.) 

Sure, time travel has been done to death, and sometimes that has a "many worlds element", but just straightforward stories of movement between parallel worlds - can't think of many.  Possible exception - sorta - Source Code (which I liked), but it only becomes clearly an element towards the end.  The only other one coming to mind is, of course, The Adventures of Buckaroo Banzai Across the 8th Dimension, but it was not a major element, if I recall correctly.  

(Oh - I should say that I was pleased that Indian Jones and the Kingdom of the Crystal Skull - about the most unduly over-derided movie of the last decade - had aliens as interdimensional travellers, as that is pretty much the preferred way that Fortean types like to think of UFO's now.   Spielberg had updated his view of UFOs appropriately.)
