Merlin Entertainments have announced that a mini-sequel to The Lego Movie will be introduced at all their Lego branded attractions worldwide - including Legoland Windsor and Legoland Discovery Centre.
The film is due to include all the main characters from the movie, and a range of 4D effects. There's no set date for the introduction of the new film, however it has been confirmed it will be introduced later this year. SouthParks has all the details so far on the news page
Looks like this could be a good addition for Legoland and will certainly draw people in. It's certainly worth keeping an eye out for the opening date for it.
