Step forward the mammary cannon-brandishing Cyborg Harpies.
The Harpies, together with the Yeast Lords, are the day-glo product of the fevered imagination of awkward Utah teenager Benjamin Purvis (Angarano).
He lives with his smothering mom (Coolidge) in - for some reason - a geodesic dome and dreams of making it big time as a sci-fi writer, a sort of home-schooled Philip K Dick.
To this end he heads for the Cletus Festival where he hooks up with budding romantic novelist Tabatha (Feiffer) and wannabe film-maker Lonnie (Jiminez), who options Yeast Lords as a no-budget action movie.
He also gets to meet his hero - sci-fi legend Dr Ronald Chevalier (Clement) - a lugubrious boor at risk of being dropped by his publisher, who pinches Benjamin's ideas and passes them off as his own.
Writer-director Jared Hess maintains the deranged fervour he brought to Napoleon Dynamite and Nacho Libre in this fitfully amusing mickey-take of pulp sci-fi and the over-earnest reverence bestowed on it by small town geeks.
Angarano is fine as the mild-mannered foil but it's Flight of the Conchord's Clement who steals the show, investing the pompous Chevalier with a voice that sounds like a catatonic Alan Rickman.
Slight and occasionally clunking, it wins through by its sheer good nature and some particularly strong playing.
Get on it.
