Declan McKenna's life is invaded by a döppelgänger - none other than Alex Lawther, from End Of The F***ing World and other good stuff - in Will Hooper's video for The Key To Life On Earth. 

Hooper has a lot of fun with the oft-noted physical similarity between the two men - and with the deteriorating relationship as initial harmony turns to disparity, and worse.

Fact is, no-one really does 'incel-style' creepiness quite as well as Mr Lawther, so it's not so surprising that his 'fanboy' character begins to take the upper hand. Will Declan get smothered by all that passive-aggression, and two become one...?

WILL HOOPER:

We're really leaning into a big internet meme that's plagued Declan for all eternity.

"Declan's likeness has always been compared to Alex Lawther's - and the comment section has always been quick to underline that fact. So with this vid we're really leaning into a big internet meme that's plagued Declan for all eternity.

"Declan came to me like, 'wassup, we've got Alex Lawther to do a movie - and I want to fight him." And I was like, 'wassup, okay, hold by beer." And then I went away and wrote this daft little idea - very loosely based on an Edgar Allan Poe short story William Wilson - that ends up with the two of them having a scrap."
