Everything to Know About Miss Crawly: the Definitive Guide to Sing's Lizard
By Maya Lin-Takahashi
Miss Crawly’s gravelly, wavering voice feels like the work of a veteran character actress. In reality, the performance belongs to Garth Jennings, the British filmmaker who wrote and directed both Sing and Sing 2. The casting was never intended to be permanent. During the early development of animated features, directors record temporary audio known as "scratch tracks" to help storyboard artists time scenes and test comedic beats.
Jennings stepped into the booth to lay down a placeholder voice for the elderly iguana. He exaggerated her vocal tremors, added sputtering gasps, and gave her an endearing, slightly confused cadence. When Illumination founder Chris Meledandri and the creative team reviewed the editorial reels, Jennings attempted to audition professional actors to replace his scratch vocals. Nobody could match the frantic, frail warmth Jennings brought naturally to the booth. The production team insisted on keeping his original vocal stems, instantly cementing the director as one of the standout performers alongside the heavyweight Sing cast.
Jennings continued the role in 2021's Sing 2, expanding her vocal range into unhinged vocal warmups and high-decibel screams. The contrast between Jennings’ behind-the-scenes directorial authority and Miss Crawly’s chaotic subservience to Buster Moon remains one of the best inside jokes at Illumination.
