“The movie is really weird in a great way. It's crazy," Lego movie writer Phil Lord has told MTV Movies.
Lord and his partner Chris Miller – both responsible for the zany CGI kids flick Cloudy with a Chance of Meatballs – are hard at work writing, designing characters and animatics for the currently untitled big screen Lego project.
The movie, confirmed in November last year, is slated for a 2014 release date.
It will mix live action landscapes with a “one inch high universe” and a cast of “thousands and thousands and thousands.”
Miller said: "In kind of a weird way it's the biggest action movie we've ever done."
With Lord adding: "And the smallest action movie of all time."
Divulging some plot details, Lord said: "It is the story of basically a young man who doesn't have a creative bone in his body and has to always build things from the instructions. He's an 'instructions worker.' In the Lego city, they build buildings, and it turns out in this universe it's illegal to build apart from the instructions.
"So what he finds out is that he's actually descendant from these like super creative Jedi-type people who are called 'Master Builders' and he has been charged with saving the universe from being frozen together by an evil bad guy, so over the course of the movie he has to unlearn all of that lame-o, uncreative stuff and learn how to build without all of the instructions in order to save the universe."
