Ananova:

The Simpsons are finally to appear on the big screen.

After years of speculation, Matt Groening and James L Brooks are leading a team of writers in developing a movie.

Work has already started on the script but the plot line is not yet fully formed, reports Sky.

It is expected to be a longer more amplified version of the show similar to the concept of the South Park movie.

Chris Meledandri, 20th Century Fox's animation chief, said the team are "very excited about the possibility of making a Simpsons movie".

"However, we are in the very early stages of developing an idea for the movie," he added.

There is no clue yet as to a release date on the movie, but it is expected to be at least two years off.
