What was the first Lego tie-in film or television production? Nowadays, it's pretty common for TV shows and films to be released by film studios in agreement with The LEGO Group and tying in to current LEGO set themes - famous examples include the recent films (The LEGO Movie and The LEGO Movie 2: The Second Part), LEGO Star Wars: The Yoda Chronicles, the Legends of Chima TV series, and Ninjago: Masters of Spinjitsu, all of which were released after 2010.
