Got his head lopped off by a sheet of glass in front of Gregory Peck.
Warner’s characters always seemed to die in the most horrible ways.
Turned to stone in Time Bandits.
Decapitated in The Omen.
Phasered in the chest in Star Trek 6: The Undiscovered Country.
Stack dropped on his face in Titanic.
Sliced through his head by an identity disk, then de-powered in Tron.
But I think the most terrifying death was in Time After Time.
About to escape in the time machine, and Herbert pulls the regulator. Causing the occupant to travel through time, uncontrolled, without the machine.
Oblivion forever.
