The much-anticipated video for Sam Smith's Bond theme 'Writing's on the wall' has been released on YouTube.

Like most Bond-associated music videos, the clip is spread throughout with cinematic moments from the forthcoming Spectre film.

And in case you had any doubts, part of this video is about British swag, as Smith delivers one of his most powerful moments in front of an epic series of Union Jack flags.

According to Billboard, Smith's song is the first Bond theme song to ever hit number one on the UK singles sales chart.
