Who: The Monster's Bride (Elsa Lanchester)
How: Castle explosion
Glad to be alive after barely surviving his first little experiment, Henry Frankenstein (Colin Clive) vows to stop building fresh psychopaths out of old corpses. But his previous creation (Boris Karloff) is still alive and another mad doctor - Pretorius (Ernest Thesiger) - blackmails Henry into making a mate for the Monster.
But the Bride doesn't much fancy the arranged marriage, so the unloved Monster blows her and the castle to smithereens... along with both doctors. Temper, temper.
