Foster removes the memory of Zoe from his family memory maps, but what about all the dozens or even hundreds of people who may have interacted with Zoe throughout her life (teachers, friends, neighbors, parents' colleagues, etc.)? Also, in this time and age when people take countless digital photos of themselves and others, how can he eliminate all evidence of her existence from the world?

In India, the film was given a UA certificate by the CBFC after following cuts were made:
