What is the name of the actor who voiced Django?

The actor who voiced Django in Ratatouille is Brian Dennehy.

Dennehy voices Django, Remy and Émile’s father and the leader of their rat colony. Django is skeptical of Remy’s fascination with human cooking and repeatedly warns him that people view rats as pests rather than as talented chefs. His caution reflects the colony’s need to survive in a hostile human environment.

Brian Dennehy’s deep, commanding voice gives Django the authority of a protective parent and colony leader. The role is part of a voice cast that also includes Patton Oswalt as Remy, Peter Sohn as Émile, and Peter O’Toole as Anton Ego. Viewers may confuse Django with other major older male characters, especially Gusteau or Ego, but those roles were voiced by Brad Garrett and Peter O’Toole.

Dennehy was a celebrated American stage, television, and film actor. His career included First Blood, Cocoon, and the television film Death of a Salesman, for which he won an Emmy and a Golden Globe.
