Just last week, the director landed Mattel’s upcoming Hot Wheels movie, and today he’s tapped Ariana Grande and Josh Gad to lend their voices to his musical Oh, The Places You’ll Go adaptation, which he will co-direct with Jill Culton.

Ariana Grande have joined Oh, the Places You'll Go!, an animated feature from Jon M. Chu and Jill Culton, based on the Dr. Seuss book.

Produced by Warner Bros., Oh, the Places You'll Go! will also feature original music by Benj Pasek and Justin Paul, the duo behind Dear Evan Hansen and The Greatest Showman. Additional cast members and plot details have yet to be announced, but the original Seuss book chronicles the whimsical and colorful adventures of a young traveler.
