In October 2008, Taylor Lautner played Christian Slater's son in the television series My Own Worst Enemy, until the show was canceled after only 9 episodes. Taylor Lautner then played Native American character Jacob Black in Twilight, the movie adaptation of the novel by Stephenie Meyer. Due to major physical changes that occur in the character of Jacob Black throughout the series, the director of Twilight's sequel, The Twilight Saga: New Moon, considered replacing Taylor Lautner with a different actor in the second film. In an attempt to keep the role, Taylor Lautner weight-trained extensively and gained approximately 30 pounds. Taylor Lautner reprised his role as Jacob in New Moon. In 2010, Taylor Lautner starred in the romantic comedy film Valentine's Day as Tyler Harrinton.
