is reporting that a Ninjago movie is in the works based on 'positive reaction' to the Lego movie trailer. Now, my reaction to the Lego movie trailer was as positive as to any trailer since Pacific Rim but I think that is because the movie looks witty and fun (and has a classic space guy), not because I really want more Lego movies for the sake of Lego movies.
I guess time will tell.
Thanks to our friends at Brickset for pointing us towards the article.
Update: Hollywood Reporter
has a few more details on the project. Brothers Dan Hageman and Kevin Hageman, who have a credit in The LEGO Movie, will be writing the Ninjago movie. They were also the writers behind the Ninjago television series on Cartoon Network so the movie should be in good hands.
