Collateral Beauty

Collateral Beauty star Keira Knightley describes how the basic concept of putting "one foot in front of the other" drew her to the drama film. The actress gushes about her co-star Will Smith, whom she says can tap into both comedy and tragedy very easily. Of the entire A-list cast, which includes Helen Mirren, Edward Norton and Kate Winslet, she calls them a "lovely bunch of people," and explains what she learned from each of them.
