Review: Ewan McDonald

Best director's prize at last year's Sundance Festival went to this tale in black-and-white of disintegrating maths genius Maximillian Cohen (Sean Gullette).

But his home-built computer might have discovered the secret to the universe in the 216-character mathematical symbol, pi.

And lots of people might want it. Didn't end-of-millennium paranoia seem so normal last year?
