London Has Fallen officially has the worst tagline ever

"Prepare for bloody hell"

Westminster Abbey blows up in the controversial teaser trailer for London Has Fallen (Lionsgate)

There's an art to film taglines: while many play it straight, using the opportunity to bolster the serious nature of a film, others use the phrase - usually a pun - to provide a knowing wink to the audience.

Unsurprisingly, there are those that fail spectacularly - step forward, London Has Fallen.

In an attempt to emulate some good old-fashioned British humour, the groan-inducing tagline on the sequel's US poster reads: "Prepare for bloody hell."

The film is a sequel to 2013 action thriller Olympus Has Fallen which follows Gerard Butler's disgraced Secret Service agent Mike Banning who must rescue the President (Aaron Eckhart) after a terrorist assault on the White House.

London Has Fallen sees Banning, now a lead agent, embroiled in an assassination attempt on multiple world leaders all assembled in Great Britain's capital for the Prime Minister's funeral.

Butler and Eckhart both return alongside Olympus co-stars Morgan Freeman, Angela Bassett and Melissa Leo. British actress Charlotte Riley (Peaky Blinders) has joined the cast as a British MI6 agent.

Last year, the film came under heavy criticism when the trailer - depicting destroyed London landmarks - was released ahead of the tenth anniversary of the 7/7 terror attacks.

London Has Fallen is released on 4 March.
