In between live-action assignments, Phil Lord and Chris Miller do animation. Cloudy with Meatballs broke out a couple of years ago. Though they aren't directing the sequel, due in September, they have supplied notes. The synopsis for their new picture:
The 3D animated adventure tells the story of Emmet, an ordinary, rules-following, perfectly average LEGO minifigure who is mistakenly identified as the most extraordinary person and the key to saving the world. He is drafted into a fellowship of strangers on an epic quest to stop an evil tyrant, a journey for which Emmet is hopelessly and hilariously underprepared.
The movie isn't stop motion, but certainly looks it.
