The two girls playing the lead parts here are total amateurs who act better actors' studio veterans. 'Level of belief beyond what any adult actors could achieve' is right, as Rebecca Miller, the director and writer, put it herself in her introduction on IFC. 'Jessica' is the story of a sort of modern day, adventurous, 'Huckleberry Finn type 10 year old girl living in the boondocks (Poughkeepsie?) with parents who are apparently former aspiring entertainer/artists who have now resigned themselves to the loss of their dreams and are having some weird, not quite clearly stated (but better for it being so)problems in their relationship. The mother succumbs to mental illness and Jessica, in order to cope creates an imaginary universe of 'order' based on the odd mixture of beliefs she's been taught in the (Christian Scientist?)household. Her only disciple is her little sister Ellie who follows her around as they do things to absolve themselves from whatever 'sins' they have committed, and 'go to heaven.' The wonderfully eccentric plot is beside the point though, because what emerges here is a unique perspective from the vantage point of a (quite mature but not vulgar) 10 year old, which automatically takes the viewer back to the forgotten soul of the 10 year old in themselves (not the silly Star Wars junkie type 10 year old soul, but the unspoiled , down-to-earth-in-its-flights-of-fancy, ten year old imagination that exists to whatever degree in all kids before it is forever eradicated). This is not easy; it is not like making a Disney movie. It requires super-involved naturalistic acting on the level of Brando and DeNiro from children. What Miller knows to her great credit is that children are much more likely to become 'themselves living in a different world' and therefore, a 'character' because they do not yet have the inhibitions that block most adult actors from believing the film world is real! The film world is as 'real' to them, as anything else once they get used to it. Jean-Pierre Leaud (for instance) has never again achieved the level of realism, as an experienced adult actor, that he did in 'The 400 Blows.' I'm glad I recorded this beautiful little film (since it's not available on video and is only shown once in a long while on IFC)because it clearly belongs in the same class of No-BS movies about childhood exemplified by 'The Little Fugitive,''Forbidden Games,''400 Blows,' and 'Au Revoir Les Enfants.'
