A great episode of Doctor Who involved time traveling to solve the mystery of a rampaging alien with none other than Vincent Van Gogh. But what made it truly great was that all that stuff was wrapped up 3/4 of the way through the episode. The last act involved the Doctor and Amy taking Vincent .... well, I won't ruin it, but it was low-key and absolutely beautiful (and it even involved Bill Nighy). At the end of the episode you can see how Vincent worked the Doctor and Amy into one of his paintings, at the beginning there was a sighting of the alien in another Van Gogh, and then later in the series, Van Gogh paints an exploding Tardis. Three Van Goghs and three involvements of the Doctor. In fiction. Right?
That's all very nice, but it (sort of) happened in real life. Recently an old Van Gogh landscape was found that was previously deemed a fake, but it looks like it's truly a Van Gogh. And in the back left of this newly discovered Van Gogh is ... a blue box?!
Close enough for impressionism. Strange but true. Source of info here.
