The Lego Movie 2: The Second Part

The Lego Movie 2: The Second Part is a 2019 animated adventure comedy film directed by Mike Mitchell and written by Phil Lord and Christopher Miller. Based on the Lego construction toys, it is the fourth and final installment in the Warner Bros. The Lego Movie film series and the sequel to The Lego Movie (2014). Chris Pratt, Elizabeth Banks, Will Arnett, Charlie Day, Alison Brie and Nick Offerman reprise their roles from the first film, with Tiffany Haddish, Stephanie Beatriz and Maya Rudolph joining the cast. The film takes place five years after the events of the previous film and follows Emmet Brickowski, Lucy and their friends, who travel into the Systar System to test their skills and creativity, while Emmet deals with a coming cataclysm known as "Armamageddon".

Development of a sequel to The Lego Movie began in February 2014. In March, it was announced that the film would be directed by Chris McKay and in October it was reported that Lord and Miller would return as the screenwriters. In February 2015, McKay was replaced as director by Rob Schrab, who in turn was replaced in February 2017 by Mike Mitchell, reportedly due to creative differences. Production for the film began in October 2017, with the majority of the cast returning to voice the characters in mid-2018, along with the new cast. As with the previous films in the franchise, the animation was provided by Animal Logic. Mark Mothersbaugh, who composed The Lego Movie and The Lego Ninjago Movie, returned to compose the film's musical score, with artists including Dillon Francis, Beck, Robyn and The Lonely Island providing original songs for the film.

The Lego Movie 2: The Second Part premiered in Los Angeles on February 2, 2019, and was released in the United States on February 8 by Warner Bros. Pictures. It received generally positive reviews from critics, although it was considered inferior to its predecessor. Despite grossing $199.6 million against a budget of $99 million, the film became the franchise's second box office disappointment after The Lego Ninjago Movie. After the film's commercial underperformance, Warner Bros. ultimately let their Lego film rights expire and eventually be picked up by Universal Pictures in 2020, making The Second Part the final installment of Warner Bros.' Lego Movie franchise and the last theatrical film based on the Lego brand until Universal released Piece by Piece in 2024.
