Into the Blue (2012)

Retired filmmaker Abraham Rabenthal (Vadim Glowna) is producing the directorial debut feature (titled Ins Blaue) of his daughter Nike (Alice Dwyer), and together are filming around Neapolitan locales with their cast and crew. Nike's film is about three young women traveling in a camper van through Italy and having individual adventures with men along the way. Eva hooks up with a monk, Josephine with a mute fisherman, and Laura, an old philosopher. After a bank rejects Abraham's application for further funding, costs needed to be cut, and two of the male characters - the monk and the fisherman, are played by the same cast member Wilhelm, and the old philosopher, by Abraham himself. But that's when things get more complicated.
