Why it worked
The video leverages the popularity of The Lego Movie and recognizable public figures (athletes and actors) dressed as iconic characters to create engaging, visually appealing content. The red carpet setting and the presentation of each character individually likely contributed to its shareability.
Summary
The video shows various individuals dressed as characters from The Lego Movie at what appears to be a premiere or promotional event. Each person is introduced with their name and the character they are portraying, set against a backdrop featuring the movie's logo and Warner Bros. branding.
