In 2008, Westwick became the new face of K-Swiss. That same year, he appeared as Joey in the horror film "100 Feet". In 2009, Westwick played the role of Randy Holt in the sequel to "Donnie Darko", directed by Chris Fisher, and guest-starred in the third season of the Showtime original series "Californication", as Chris "Balt" Smith, a student who was fascinated with vampire literature. In May 2009, he was attached to play Heathcliff in the film adaptation of "Wuthering Heights". However, in January 2010, director Peter Webber left the project, which was then passed into the hands of Andrea Arnold. This directing change caused the roles to be recast.
