The movie that I watched was Mr. Nobody (2009). It is about Nemo Nobody (yep, that’s his name) a 117-year-old- man who is the last mortal on Earth after the human race achieved quasi-immortality. Before he dies, he recounts his “past” when he had to make a critical decision and we get to examine the speculative narrative of alternative life paths he could have lived with three different women. Essentially, it is a story about choice and the ‘what ifs’ of life.
A small design decision that I noticed was the use of genetic pigs as the immortality technology in the year of 2092. Every person (except Nemo) has genetically compatible pet pigs. Instead of food, the pigs are harvested for stem cells which allow an endless renewal of cells and thus, everlasting life for humanity.
