This world-changing event is made even stranger when she realizes that the monster mirrors her every move, and that she actually is in complete control of the giant beast.
Colossal centers on Gloria (Anne Hathaway), whose life has pretty much fallen into complete and utter disarray.
One day she wakes up from a bender to find that a giant monster has emerged and is running loose somewhere in the world.
That trailer pretty much spells out everything that you need to know.
