Here are actual bloopers from "The Lego Movie". (Apparently they took REAL bloopers from the voiceover actors in the studio, and animated new scenes to match them using the characters from the movie.)
By the way, it took A LOT of REAL LEGOS to make "The Lego Movie". How many? A grand total of 3,863,484!
A lot of the movie WAS CGI, though. The filmmakers say that if they'd made the movie ONLY with real Legos, it would have taken 15,080,330 unique pieces!
