Presented as a memory flashback by a woman named Lena, The Last Mimzy is the story of a distant future's attempt to avert a catastrophic ecological disaster that has destroyed their world. High tech devices, masquerading as toys, are sent back in time into the hands of Noah and Emma, two children who live with their parents Jo and David in early 21st century Seattle. The "toys" are mostly incomprehensible to Emma (Rhiannon Leigh Wryn) and Noah, except for what appears to be a stuffed rabbit named Mimzy. Sensing the strangeness of the devices, the children initially keep their discovery a secret from their parents. Loosely adapted from the 1943 science fiction short story "Mimsy Were the Borogoves" by Lewis Padgett (the pseudonym of husband and wife team Henry Kuttner and C. L. Moore). The film features Timothy Hutton, Joely Richardson, Rainn Wilson, Kathryn Hahn, Michael Clarke Duncan, and introducing Rhiannon Leigh Wryn and Chris O’Neil as Emma and Noah.
