Peter Cullen, Voice of Optimus Prime and Eeyore, Dies at 85

Q: Did the legendary voice actor behind Eeyore and Optimus Prime leave behind any unreleased performances for fans to hear one last time?

There is no confirmed report yet that Peter Cullen left behind any unreleased performances that fans are certain to hear after his death. The available news coverage about Cullen’s death focuses on his legacy, family statement, and career highlights, including Optimus Prime, Eeyore, and other major roles. The additional material also does not identify any officially announced posthumous film, television, game, or animation performance waiting for release. That said, the absence of an announcement does not rule out the possibility that unreleased work exists. Voice actors often complete recording sessions well before a project is made public, especially for animated series, games, audiobooks, and dubbing work. Cullen was active through 2026, and a recently edited biography entry lists his career as lasting until this year, which suggests he may have continued working close to the end of his life. One possible lead in the broader search material is a GraphicAudio listing connected to a 2026 dramatized adaptation, but the supplied content does not clearly confirm Cullen’s participation in it, so it cannot be treated as verified evidence of a final unreleased performance. For now, the most accurate answer is that no last unreleased performance has been publicly confirmed. Fans will need to wait for announcements from studios, publishers, or his representatives to know whether any posthumous roles are still to come.

Peter Cullen died Wednesday at his Los Angeles home at 85, his family saying the Canadian voice actor passed peacefully surrounded by relatives.
Cullen became best known as Optimus Prime, first voicing the Transformers leader in the 1984-87 animated series and returning for Michael Bay’s film franchise, whose 2007 launch grossed $709.7 million worldwide.
He also gave voice to Eeyore in multiple Winnie the Pooh projects and built a wider genre résumé that included King Kong, Knight Rider’s K.A.R.R. and the Predator creature’s clicking sounds.
Montreal-born Cullen said he modeled Optimus Prime on his older brother, a decorated Vietnam veteran, and his decades-long work made him one of the most recognizable voices in modern animation and sci-fi.
