In 2016, Robert McIntyre, a graduate of MIT, became the first person to freeze and then revive a mammalian brain—that of a white rabbit. “When thawed, the rabbit’s brain was found to have all of its synapse, cell membranes, and intracellular structures intact.” The film, Realive, made that same year, is a fictional story about a man with terminal cancer who commits suicide to be frozen and revived when his illness could be cured. In the context of McIntyre’s scientific work, the film’s sci-fi demeanor belies the very real possibility that cryogenics could realistically alter fundamental assumptions about life and death even just later in the same century. What the film says about the life and death is timeless, however, in terms of philosophical value.
