In New York City, the crocodiles are supposed to stay in the sewers, where they belong, but Lyle is no ordinary croc.

In a trailer for the upcoming Lyle, Lyle, Crocodile, based on the 1962 children’s book The House on East 88th Street and its eponymous 1965 sequel by Bernard Waber, Lyle is a singing, dancing, scarf-wearing crocodile who just happens to live in the upstairs bathroom of the Primm family’s Victorian brownstone.

Lyle is voiced by singer Shawn Mendes, and is only fierce when he’s performing, much to the relief of the Primms, played by Constance Wu, Scoot McNairy and Winslow Fegley as young Josh, who votes to keep Lyle against his parents’ better judgement.

The two become fast friends, but when Lyle’s existence is threatened by evil neighbor Mr. Grumps (Brett Gelman), the Primms must band together with Lyle’s charismatic owner, Hector P. Valenti (Javier Bardem), to show the world that family can come from the most unexpected places and there’s nothing wrong with a big singing crocodile with an even bigger personality, according to the movie’s official description.

The movie promises an impressive soundtrack: Benj Pasek and Justin Paul, who are also known for their work on La La Land and The Greatest Showman among many others, teamed up with Mendes, Ari Afsar, Emily Gardner, Xu Hall, Mark Sonnenblick, and Joriah Kwamé to compose the songs for the film. Lyle, Lyle, Crocodile is directed by Will Speck and Josh Gordon and screenwriter Will Davies who penned the film’s script. 

Unlike most movies of late, Lyle, Lyle, Crocodile will open earlier than planned; it was scheduled for mid-November but now families can get their Lyle fix on October 7th, only in theaters.
