Did you spend your childhood making Lego cars, planes, trains or spaceships? Then Lego wants to see your designs for its new 3D movie, Lego: The Motion Picture.
The iconic toy brick company is seeking unique and original vehicle designs - and it's offering the chance to win $1,000 for the best.
The winning creation will be considered for a spot in the Warner Bros movie, which currently being directed by Phil Lord & Christopher Miller and scheduled for cinematic release on 28 February 2014.
The vehicles must be built using only Lego pieces, and the challenge the company has set is to "build a custom vehicle - whether a car, plane, boat, rocket ship or any kind of transportation imaginable - while making it look as if it were re-purposed from parts of something else, such as a castle or a taco stand."
There are separate competition categories for kids, teens and adults, and the tagline reads: "From your mind to the movie - dream it, build it, share it and win!"
The competition is open to residents of US and Canada, while there will be separate contests in other territories - details of the UK competition (open to under-14s only) can be found here.
