"I'm playing Jiminy Cricket in Guillermo del Toro's version of ‘Pinocchio'. That I had started working on before I left for New York, so some of that is recorded. Of course it's stop-motion animated so it's going to take them a great long time to make that film," he said.

"But my first part, which is recording his dialogue, is sort of done. There may or may not be a song that has to be recorded. I'm not sure I'm at liberty to discuss that," he added.

The movie is set for release in 2021, and will narrate a darker story than the Disney animated classic.

According to Netflix, the idea for the film was first conceived in 2010, and will be based on the darker story of Pinocchio found in a 2002 book illustrated by Gris Grimly.
