In an press junket interview with Sky News earlier this week, during her visit to the UK to publicize the release of action comedy "Killers", Katherine and director Robert Luketic spoke about the innovative use of social media and the internet to promote the movie.

The duo also teamed up to speak with the Daily Star at the European premiere in Leicester Square, where Katie explained that when it came to the action scenes in the movie, her stunt double stepped in - "I did climb a couple of fences and I did all my own walking," she joked.
