Or "Martian timeslip". In fact "blade runner" is a pretty poor adaptation of the book (but a great film, imo). I'm not sure most of pkd would benefit too much from a "direct" film adaptation...

I loved the man in the high castle for many of the changes and the overall style - but it seems the writers got a bit lost trying to round off the open ended story and fill in some blanks. Small wonder, considering the book.
