The Secret Adventures of Tom Thumb is a 1993 British independent stop-motion/pixilation adult animated science-fantasy dystopian adventure horror film directed, written, shot and edited by Dave Borthwick, produced by bolexbrothers studio and funded by Richard Hutchinson, BBC, La Sept and Manga Entertainment, which also distributed the film on video.

[1] The story follows the tiny Tom Thumb as he is abducted from his loving parents and taken to an experimental laboratory, and his subsequent escape.

Inside an artificial insemination factory, a mechanical wasp hovering around the establishment is crushed to death by the machinery's gears, causing its vitals to drop into one of the jars on the conveyor belt.

This results in a woman giving birth to a thumb-sized fetus-like child in her and her husband's house in a grim and slum urban town.

Outside, a man in a black suit witnesses the whole scene and goes to an alley to encounter Pa Thumb, who picks up a ventriloquist box-shaped doll house to make his son's bedroom.
