PBS Nova: Darwin's Darkest Hour (Trailer)

In 1858 Charles Darwin received a letter from naturalist Alfred Wallace, explaining his own theory of evolution. This was the trigger event that led to the publication of Darwins seminal theory on the origin of species.

Starring Henry Ian Cusick (Lost) and Frances OConnor (Mansfield Park, The Importance of Being Earnest, Steven Spielbergs Artificial Intelligence: AI), the two-hour drama will air in the U.S. on the PBS signature series NOVA. Scheduled to air Oct. 6, 2009, Darwins Darkest Hour will coincide with the 200th anniversary of Darwins birth and the 150th anniversary of his seminal work On the Origin of the Species.
