“When the Primm family (Constance Wu, Scoot McNairy, Winslow Fegley) move to New York City, their young son Josh struggles to adapt to his new school and new friends,” the official description reads.

“All of that changes when he discovers Lyle — a singing crocodile (Mendes) who loves baths, caviar, and great music — living in the attic of his new home. The two become fast friends, but when Lyle’s existence is threatened by evil neighbour 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.”

Joining Pasek & Paul in writing songs for the film are Ari Afsar, Emily Gardner Xu Hall, Mark Sonnenblick and Joriah Kwamé. Will Speck and Josh Gordon direct the film written by Will Davies.

“Lyle, Lyle, Crocodile” opens in theatres October 7.
