The Last Mimzy is a 2007 science fiction family film directed by Bob Shaye and loosely adapted from the acclaimed 1943 science fiction short story "Mimsy Were the Borogoves" authored by Lewis Padgett (the pseudonym of husband and wife team Henry Kuttner and C. L. Moore). The Last Mimzy centers on two children, Noah (Chris O'Neil) and Emma (Rhiannon Leigh Wryn) Wilder, who develop preternatural powers when they encounter a mysterious box containing strange devices, presumed to be toys.
Presented as a flashback, The Last Mimzy is the story of a distant future's attempt to find a solution, through time travel, to 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. The children and their parents, Jo (Joely Richardson) and David (Timothy Hutton), live in early 21st century Seattle. The "toys" are mostly incomprehensible to Emma 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.
Interaction with the devices causes the children to develop increased intelligence and psychic capabilities, including teleportation of objects, telepathy, levitation, telekinesis, and the ability to control bugs. Emma becomes emotionally attached to Mimzy, from which she learns how to further operate the devices. The children's unusual abilities and Emma's obsessive attachment to Mimzy soon alert their parents and schoolteachers to the devices. Later, a power black-out of the entire Pacific northwest caused by the toys alerts the Federal Bureau of Investigation (FBI) to their activities as well. The family is held for questioning, and it is revealed that Mimzy is actually an advanced form of artificial life utilizing nanotechnology. Mimzy has brought a message from humanity's future, where Emma explains that pollution has corrupted humanity's DNA. Many rabbits like Mimzy were sent to the past, but none had successfully returned; Mimzy is the last one remaining. Mimzy explains to the children that they must use the toys as a time machine to return her to the future with uncorrupted 21st century DNA, which the people of the future can use to correct the damage to their DNA caused by the ecological problems.
