Overview
- The death certificate obtained by TMZ shows Peter Cullen died on Aug. 26 and lists cardiac arrest following respiratory arrest with a malignant neoplasm of the lower lung lobe as the underlying cause.
- The official filing names additional contributing conditions reported in coverage, including cerebellar metastasis, hypoxia, chronic obstructive pulmonary disease, hypertension, and hyperlipidemia.
- Cullen’s family said he passed peacefully surrounded by loved ones and asked fans to honor his legacy, and funeral arrangements have been reported for a Sept. 9 burial at Forest Lawn.
- Hasbro and Fathom confirmed a 12‑minute short, Optimus Prime: Awakening, will accompany select 4K anniversary screenings beginning Sept. 17 and includes Cullen’s final original Optimus Prime performance with Frank Welker returning.
- Cullen’s decades‑long work as the voice of Optimus Prime and Eeyore made him a defining figure for multiple generations, and the re-release with his final performance is likely to serve as both a tribute and a focal point for fan mourning.
