We frequented King's Cross Station several times as we travelled around London on PT.
Platform 9 3/4 from Harry Potter was filmed here, somewhere near the spot in the second photo.
The sign in the first photo was not in the actual filming spot, but was available for photo opportunities.
There have been other movies filmed at King's Cross Station, however the only one I have seen is the Imitation Game, about Alan Turing (Benedict Cumberbatch), a genius mathematical code breaker during the second World War.
