Preview: Darwin's Darkest Hour

No, that's not Desmond in another Lost flashback. But Henry Ian Cusick, one of our favorite actors from that crazy island family, has been cast as Charles Darwin in National Geographic Television's first scripted film, which will air next week on PBS. Darwin's Darkest Hour celebrates the famous scientist's discoveries and trials, and shines light on his personal life. The two-hour drama, presented in conjunction with NOVA, airs Tuesday, October 6 (check local listings).

If you'd prefer to see the show on the big screen, plan to attend the premiere of the film at National Geographic headquarters in Washington, D.C. on October 5. The film will be followed by a discussion with director John Bradshaw, scriptwriter John Goldsmith, and executive producer John Bredar.
