Knightley reduced workload due to 'exhaustion'

Keira Knightley decided to reduce her movie workload because she was suffering from "exhaustion".

The 'Never Let Me Go' actress – who in the past has admitted she can see herself moving away from acting altogether – made the decision she needed a year off from lead roles after she was left drained after playing Georgiana Cavendish in 2008's 'The Duchess'.
