Robin Dunne was born in Toronto, Canada. He attended Etobicoke School of the Arts, a performing arts high school where he began his acting training.
In 1994, Dunne got his first major television role, playing the troubled son of Judith Light in Against their Will: Women in Prison. This first break led to pivotal roles in the television films Love and Betrayal: The Mia Farrow Story with Patsy Kensit, and A Husband a Wife and Lover; as well as a supporting role in the feature film Brother’s Destiny alongside Mickey Rooney, Kris Kristofferson, Danny Aiello and Charles Martin Smith.
After working steadily for several years, in 1998 Dunne landed a role in the John Woo-produced blockbuster The Big Hit with Mark Wahlberg, Lou Diamond Phillips, and Christina Appelgate. With his breakout performance of Gump in the film, Dunne gained the attention of Roger Kumble and Neal Moritz who cast him in the short-lived Fox series Manchester Prep. Dunne then went on to join the cast of Dawson’s Creek, playing love-interest to Katie Holmes, and appeared in Showtime’s Dead Like Me as well as starring in The Skulls 2, the award-winning Borderline Normal, and Hallmark’s Mark Twain’s Roughing it alongside James Garner, Ned Beatty, and Adam Arkin. Dunne has since appeared in Charles Martin Smith’s The Snowwalker, Just Friends with Ryan Reynolds, Species 3, and ESPN’s Codebreakers with Scott Glenn.
In 2005, Robin co-wrote the Nickelodeon films Roxy Hunter and the Mystery of the Moody Ghost, and Roxy Hunter and the Secret of the Shaman. These first two films spawned a franchise that has led to his co-writing the third and fourth installments in the series, Roxy Hunter and the Myth of the Mermaid, and Roxy Hunter and the Horrific Halloween. He has also co-authored the novels for Penguin Books.
On stage, Robin has performed his one-man show Safe Place at the Alley Workshop Theatre in Toronto, as well as at the Writer’s Week Festival in Listowel, Ireland. He has since written another play entitled B Movie Messiah in the City of Oblivion, which he plans to perform in Los Angeles in the fall of 2008.
Currently, Robin can be seen in the upcoming film Jack and Jill vs The World out in theatres spring 2008 as well as the Sci Fi channel series Sanctuary playing psychiatrist Will Zimmerman, alongside Amanda Tapping and Emilie Ullerup. Dunne will also write for the series.
