What makes 'Lost in New York' so fascinating is that it is a very open, personal movie, unlike 'The Living Dead Girl' for example which needed to satisfy certain expectations of the particular audience it was aimed at.
The circular traveling across space and time is done with a magical device, a round wooden thing called Moon Goddess, also impersonated by a dancer, an actress you may remember from 'Emmanuelle 6'.
The film thus completed to a length of almost an hour tells us about two young girls who imagine they might be grown up and see New York, later to meet again with their memories as old women, returning to their days of youth. The rather spontaneously shot footage he brought home to France was extended by shots on the pebble beach familiar to all Rollin fans. 'Lost in New York' happened by chance when director Rollin had the possibility to visit New York with only 2 actresses coming along.
