This week Survival International will launch a new campaign to highlight the plight of the Awá, backed by Oscar-winning actor Colin Firth. In a video to be launched on Wednesday, Firth will ask the Brazilian government to take urgent action to protect the tribe. The 51-year-old, who starred in last year's hit movie The King's Speech, and came to prominence playing Mr Darcy in the 1995 BBC adaptation of Pride and Prejudice, delivers an appeal to camera calling on Brazil's minister of justice to send in police to drive out the loggers.
