L'assoluto naturale (internationally released as He and She and She and He) is a 1969 Italian drama film directed by Mauro Bolognini. The plot focuses on a mysterious romance involving an uninhibited woman (Koscina) and a dour photographer (Harvey), shot in strange modernist interiors and abstract "sports car on a highway to nowhere" exteriors. The work of cinematographer Ennio Guarnieri in this film has been referred to as "one of the cornerstones of Italian photography in the sixties".
