While a cause of death was not immediately made public, his agent Kevin Motley informed the Hollywood Reporter of the news.
Cullen’s family also provided a statement, saying that the actor “passed away peacefully, surrounded by his loving family–and held in the hearts of his many friends and countless fans worldwide.” His family asked “that you honor his remarkable legacy by serving your communities and leading others with compassion, integrity and loyalty and always remember ‘be strong enough to be gentle’.”

In the realm of Hollywood, Cullen has also played iconic roles like the Predator in Predator (1987) and King Kong in King Kong (1976).
