Pegg is no stranger to Bad Robot productions, having done four Mission: Impossible films, three Star Trek films and Star Wars: The Force Awakens with the company.
Levitt had previously starred in director Rian Johnson's Brick and Looper, and had a cameo in The Brothers Bloom, so there was no way he wasn't appearing in the man's Star Wars movie. He voiced the alien Slowen-Lo on the casino planet Canto Bight, who rats out Finn and Rose for parking on the beach.
