Originally from Boston, TJ Thyne grew up doing theater and studying acting throughout the United States and British Columbia. At a young age, Thyne landed several lead roles in theater productions around the country, including "The Secret Garden" at the Dallas Theater Center and the Off-Broadway production of "Van Gogh" at New York's Mint Theater Company.

Thyne graduated from the USC School of Theater, where he received his B.F.A. in Acting. Soon thereafter, he landed more than 50 guest star and recurring roles on television series, including "Friends," "Cold Case," "Boston Legal," "Nip/Tuck," "CSI: New York," "CSI: Crime Scene Investigation," "Huff," "The O.C.," "24" and more.

In 2001, Thyne founded Theatre Junkies Productions, which produces theater and films in Los Angeles. His most recent project, a feature film called "Shuffle," was written and directed by award-winning fellow Theatre Junkie Kurt Kuenne and follows the story of a character named "Lovell Milo," played by Thyne, who begins experiencing his life out of order. The film  includes cameos from a few familiar faces from the cast of BONES. Thyne last collaborated with Kuenne on their black & white short film series that included the internet cult favorite "Validation," which has won over 20 film festivals around the world and has more than five million hits on YouTube. The newest Theatre Junkies production is a new series of shorts in a collection written & directed by Thyne called "The Moment Series". This series has begun showing in over 30 international film festivals this year.

Thyne's feature film credits include the roles of "Stu Lou Who" in "How the Grinch Stole Christmas" with Jim Carrey, the young lawyer "David Foil" in Steven Soderbergh's "Erin Brockovich" and "Gerald" in "How High" with Method Man and Redman.
