This caught my interest for a couple of reasons.
First of all I know a little bit about the background to this having read some John Gribbin books! Arthur Eddington went on an expedition to Africa in 1919 to photograph a star during an eclipse. The position of the star appeared to move and therefore proved that the sun's gravity could bend light therefore Einstein's theory held up.
The other point of interest is that Rebecca Hall is playing Winnie Eddington. Rebecca has caught my eye in a number of things including one of my favourite movies, The Prestige, and last years Joe's Palace on the BBC.
Hopefully it will be as good as Copenhagen, another BBC science-inspired drama from a few years ago that started a pre-Bond Daniel Craig. That one looked at the WW2 meeting between the Danish Niels Bohr and German Werner Heisenberg who were working on the atomic bomb on opposite sides.
Einstein and Eddington is written by Stephen Moffat so it should be good. His Doctor Who scripts have been far superior to anything else on TV.
Oh, yes, that David Tennant fella plays Eddington.
Einstein and Eddington is on BBC2 at 9:10pm on Saturday 22 November 2008.
