Even though the first movie was a success, it seems that The LEGO Movie sequel is taking a while to put together. The 2014 movie was originally supposed to get a sequel in May of 2017, but that got pushed back to 2018. The movie got pushed back again to 2019, and then got a new director.
Despite all that, it looks like the sequel is still coming and today we got a title for it… and it looks like the release date hasn't changed. The title for the next movie is: The LEGO Movie 2: The Second Part.
If none of those things change, you can go watch The LEGO Movie 2: The Second Part on February 8, 2019.
