Barry Summers is an actor who portrays the role of Jack Hodgins/Dr. Don Yagher in the movie "Bone of Contention". However, when a murder was committed on the set of the film while Booth and Brennan were observing the production, he revealed that he also had a degree in botany, microbiology, and entomology- although he went into acting as a career as he enjoyed it more- allowing him to actively serve as Brennans on-site 'intern' while the rest of the team were in Washington.
