TODAY on "Q" 

-- The prolific and creative Grammy-winning singer and producer Pharrell Williams has drawn attention lately as one of the rare musicians to compete against himself -- with the songs Blurred Lines and Get Lucky -- for a number 1 spot on the Billboard charts. Pharrell joins Jian to discuss the relationship between design and music, the art of collaboration, and the new Toronto exhibition of playful art he's curated called This is Not a Toy.

A star of the Lord of the Rings series, he also has a history of roles in art films, and is a frequent collaborator with filmmaker David Cronenberg in A History of Violence, Eastern Promises and A Dangerous Method. Jian speaks to a contemplative Mortensen about his roles, fears and creative goals.
