Four Dimensions of Greta is a 1972 British sex comedy film directed and produced by Pete Walker, featuring four 3-D film sequences. It was the first British film to use 3-D, and the tagline on the poster read, "A girl in your lap". The film is also known as The Three Dimensions of Greta. Plot Hans, a young German journalist arrives in London to write an article about au pair girls but is requested by friends to investigate the whereabouts of their teenage daughter Greta. He interviews four individuals who all paint distinctly different pictures of the missing girl - each revealing a different aspect or dimension. These reminiscences constitute the film's 3-D sequences. Hans finally tracks down Greta and discovers she has been kidnapped by an East End gangster. Cast Hans Weimar ... Tristan Rogers Sue ...

Critical reception The Spinning Image wrote, "thrusting a banana at the camera is evidently not as erotic as director Pete Walker might have hoped." The Digital Fix noted an "amusingly daft sex film" DVD Drive-in said, "although the title boasts "3-dimensional," the characters are almost all 1-dimensional...Only Robin Askwith (star of Horror Hospital and numerous "Confessions" and "Carry On" flicks) turns in a memorable performance as a shabby footballer romantically tied to Greta."
