David Hewlett was born in Redhill, England, and moved with his family to Canada at the age of four. While attending high school in Toronto, he launched his acting career, starring in student films by Vincenzo Natali. He dropped out of high school in his senior year to pursue careers in acting and computing, beginning his acting career in 1984 at the age of sixteen. Before his acting career took off, he ran Darkyl Media, a web site design firm, and also founded Fusefilm.com, an internet community for filmmakers.

David has appeared in many horror films, such as “The Darkside” and the cult favourites “Scanners II: The New Order” and “Pin”. He also guest starred in several television series. In 1996, he landed the role of Grant Jansky on “Traders”, while in 1997 he worked with Natali again, starring in his critically acclaimed thriller “Cube” as Worth the architect. Later collaborations with Natali include his role in “Splice”.

An avid science fiction fan, David has been quoted saying that “Doctor Who” first sparked his love for the genre, inspiring him to make science fiction films on his 8 millimetre camera with friends in Britain. His early dreams of working in science fiction became a reality when he was first cast in a guest role on “Stargate SG-1” as Stargate expert Rodney McKay, eventually growing the character into a starring role on “Stargate Atlantis”.

Since then, David has kept busy in film and TV, writing and directing “A Dog’s Breakfast”, starring himself, his sister Kate Hewlett, his dog Mars, and “Stargate Atlantis” co-stars Paul McGillion, Christopher Judge and Rachel Luttrell. He also appeared as a guest star in the first episode of “Sanctuary”, a show produced by and starring his fellow Stargate alum Amanda Tapping, and has created a YouTube channel named “Fanatical”. He starred in “State of Syn” and appeared in the recurring role of Tabor Calchek on “Dark Matter”, a merchant who also serves as the team’s handler, and in 2017 he made “HEWLOGRAM”, a sci-fi comedy short showcasing the film making and special effects tools of Red Giant.


David’s many other roles have included appearances on “Murdoch Mysteries”, “Incorporated”, “Suits” and Hellcats, while he has had prominent supporting roles in “Rise of the Planet of the Apes” and “The Shape of Water”.
