Peter Cullen, the voice actor who plays Optimus Prime, also played Prime in the TV series the movie was based on. Cullen honestly had no idea how popular the character was until the public backlash over Optimus Prime's death in the movie, as the studio never sent him any of the fan mail addressed to Prime. But to this day, he consistently cites Optimus Prime as his absolute favorite role. He had a rare chance to reprise this role in the 2007 film Transformers, a 'reimagining' of the original classic.
