The LEGO Movie 2 Trailer: 7 Easter Eggs & References You Might Have Missed
5. Westworld
A very subtle reference shows its head when Emmet leaves the saloon where he bought his coffee. Behind him is a samurai, a knight, and a cloaked figure.
In the finale of season 1 of Westworld, it is teased that there could be a samurai setting for another park in the series. Similarly, the movie the series is based on has a Medieval world as well as a western one.
The main highlight of this reference is likely the samurai in a Western setting, doing what the Westworld TV show hasn't done yet in combining the two.
The historical figures don't look too happy at Emmet's musical choice however, so it's unlikely they'll be his allies in the story.
