The film is the third in the 'Blood and Ice Cream' trilogy, following 2004's Shaun of the Dead and 2007's Hot Fuzz.
The stills - via Empire and IGN - show off Pegg's new 'gothic' look, as well as the all-star British supporting cast.
The World's End tells the story of a group of childhood friends who are persuaded to go on a legendary pub crawl by Gary King (Pegg), a 40-year-old who is still desperately clinging on to his teenage years.
However, the pub crawl takes on a whole new significance when the world comes under threat from an as-yet unidentified source.
The gang includes Martin Freeman as an estate agent, Paddy Considine as a rocker turned architectural consultant, Nick Frost as a successful lawyer and King's former best friend, and Eddie Marsan as a car dealer.
Wright told IGN that the film is "more nostalgic" than the others in the trilogy, saying: "I think a lot about my adolescence and my teenage years and things I'd do differently. I have grand fantasies of going back in time and doing things better. Back to when I was 15 or 16.
"So there's an element of that - whether it's healthy to look or go backwards. That's kind of what the theme of the film is."
