Farrow praises 'extraordinary' Spielberg

Mia Farrow has praised Steven Spielberg's decision to leave his position as artistic director for the 2008 Olympic Games in Beijing, China.

The campaigning star has been urging Spielberg to quit the post for months, because of China's trade links with Sudan - where more than 200,000 people have been killed and more than two million turned into refugees by famine and war, since civil war broke out in 2003.
