Wright held the premiere of his film The World's End at The Embassy in 2013, alongside stars Simon Pegg and Nick Frost, as well as co-star Martin Freeman.

Kylie Klein NIxon Sir Peter Jackson, Ansel Elgort and Edgar Wright answer questions during a Baby Driver Q&A at The Embassy cinema in Wellington.

Freeman was in New Zealand filming The Hobbit trilogy.

The World's End was the final instalment in Wright's so-called Cornetto Trilogy, which also includes zombie rom-com Shaun Of The Dead and buddy-cop comedy Hot Fuzz.

Baby Driver is expected to be a huge hit this year - but its not your average film.

Wright told the packed screening that the script and action sequences were written around a specific playlist, with each action sequence and car chase being choreographed to a song.

Music was played on set all the time, while shooting scenes were choreographed to a specific song's beats, as the weapons were often so loud to hear the music on set.

There were more than 40 songs on the soundtrack, including John Spencer Blues Explosions' Bellbottoms, The Damned's Neat Neat Neat, and Queen's Brighton Rock.

Moderating the Q&A, Sir Peter Jackson, a Beatles fan, admitted he hadn't heard any of the songs in the film before seeing it.

"All the songs in here, they're completely new to me," Jackson said.

"There were no Beatles songs so that's quite sad."

Wright said he avoided major titles for licensing reasons.

"In theory, Baby You Could Drive My Car would be a good one," he said.

During the Q&A session Wright ​said a sequel, or prequel, was on the cards.

"It's something that is being talked about," he said.
