Actors Matthew Goode and Toni Collette are joining the cast of the indie comedy "Birthmarked," which is currently in production in Montreal. Directed by Emanuel Hoss-Desmarais from a script by Marc Tulin, the film centers on a pair of prestigious scientists who conduct an experiment which they hope will revolutionize the understanding of human identity on three children, only to ultimately gain a more profound understanding on the nature of humanity and the true meaning of family.
