This Warner Bros. movie was released in 1984. This fantasy movie is about an odd creature called Mogwai, a pet for a young boy, that has the ability to copy or clone itself.
This is a comedy, horror movie where a boy is gifted a creature called 'Mogwai' by his father. Unknowingly, the boy breaks three rules related to the creature, resulting in it getting cloned multiple times and bringing havoc.
As that time, CGI was not so advanced, and all the small monster creatures used were animatronics.
