Variety reports that Warner Bros. is developing a movie that is set around Lego and its component building blocks.

Writing the screenplay will be Dan and Kevin Hageman. It is believed that the project will be family comedy and it will mix live action and animation. Warner Bros. is revealing very little about the plot, but it is being called "an action adventure set in a Lego world."

Dan Lin (Sherlock Holmes) is going to be producing the film.

A Lego film has proved quite elusive for directors and producers for several years. Lego has been approached many times and they have turned down the ideas. They have only done direct-to-DVD animated fare that is based on its line of Bionicle toys.

Lego liked the idea that Lin and the Hageman brought to the film. Specifically, "a fun factor, creativity and that imagination has no boundaries," Lin said.

Apparently, the development process has been happening for a year. The writers and the producer have been going back and forth to Denmark so they could work with Lego on the project.
