La La Land 2049 trailer: This Blade Runner/La La Land mash-up needs to exist

Movie mash-ups used to be made with haste, slapped together on iMovie and feeling very rough round the edges. Now, however, they're pretty much an art form.

Ryan Gosling vehicles La La Land and Blade Runner 2049 collided this week, two very stylised movies all about atmosphere.

YouTuber and VFX creator TheDoctorOfWill went to considerable lengths with it, adding a fallen Oscar statuette to K's desert walk (a reference to the Moonlight snafu) and a neon sign for Seb's bar to the abandoned building in which K finds Harrison Ford's character.

Emma Stone then emerges from the darkness of the corridor instead of Ford. as La La Land's signature whistled melody is heard.

Sadly, Damien Chazelle's traffic jam dance scene isn't remade with flying cars, but it's still a pretty slick vision.
