Simon Pegg says he loves writing with Edgar Wright and the pair of them have refined their technique over the years.
The World's End sees the pair work together for the third time after penning Shaun of the Dead and Hot Fuzz. Pegg will also star in the movie with Nick Frost while Wright is back in the director's chair.
And Pegg believes that The World's End was the smoothest writing process of the three films as the pair have really got use to working together.
Speaking to Collider the actor said: "We have refined our technique over the years although it remains pretty similar to the other two. We still use a flip chart to lay out all our ideas.
"We start on a large canvas and then refine and refine until we have the screenplay we want to shoot. We never stop writing, all through the shoot and even through the edit.
"Once we have all the visual materials, things sometime change, which require rewrites or cuts.
"I feel like this one was the smoothest and most efficient. I love writing with Edgar, I think we bring out the best in each other."
The World's End is the first time that Pegg, Frost and Wright have worked together since Hot Fuzz and they have brought together a great cast that includes Paddy Considine, Martin Freeman and Rosamund Pike.
As for Pegg he is currently sitting top of the UK box office with his latest movie Star Trek Into Darkness - where he reprises the role of Scotty.
The World's End's End is released 19th July.
