In The Iron Giant, which actor provides the voice of the giant robot?

In The Iron Giant, Vin Diesel provides the voice of the giant robot.

The Iron Giant is an animated 1999 science-fiction film directed by Brad Bird and based on Ted Hughes’s 1968 novel The Iron Man. Diesel voices the enormous extraterrestrial machine, whose limited spoken dialogue and expressive vocal sounds help create a gentle character despite the robot’s destructive military design.

The story is set in 1957 during the Cold War. A young boy named Hogarth Hughes discovers the robot and becomes his friend, while the United States government treats the mysterious visitor as a potential threat. The film’s central conflict contrasts the Giant’s intended weapon-like function with his ability to choose kindness.

Vin Diesel was already known for film acting before the movie, but The Iron Giant predates his later association with the Fast & Furious franchise. Brad Bird later directed The Incredibles and Ratatouille.
