American actor, known as Dr Silberman in the Terminator films, who gave face and voice to the entity Nagilum in the Next Generation episode Where Silence Has Lease.
Earl Boen (1941 to 2023) was an American actor and voice performer. He is best remembered as the sceptical psychologist Dr Peter Silberman in the first three Terminator films, and he had a long second career voicing characters in animation and video games.
In the second-season Next Generation episode Where Silence Has Lease he plays Nagilum, a powerful being who traps the Enterprise-D in a void and appears as a distorted face on the viewscreen.
Nagilum proposes to study death by killing up to half the crew, which drives Picard to set the auto-destruct before the entity declares its curiosity satisfied.
