Science in the movies: From microscope to multiplex - An MRI scanner darkly p922

There's more to science at the movies than Lex Luthor's attempts to synthesize kryptonite. In the first of two features on film, John Whitfield looks at how a cinematographic technique can provide insights into the perception of reality. In the second, Alison Abbott meets Ben Heisenberg, a director whose first film is a taut moral fable of laboratory life.
