 In the remake, the pods and flowers stay dormant until the humans are asleep.The alien duplicates are also far more overtly emotionless than the ones in the original film, to the extent that, apart from "leader" duplicates such as Dr Kibner, they do not appear to be able to even feign emotional states and reactions.It is unclear whether the duplicates eat, though we see one drinking water in a scene at Elizabeth Driscoll's apartment..

As in the 1978 film, these pod people emit the same high-pitched scream to indicate non-converts among them.
