Smith was discovered by a talent agent while acting in a school play, Man of La Mancha. After a few years of working in film and television, he landed the role of Terry "The Toad" Fields in George Lucas's 1973 film American Graffiti, a role he reprised in the film's 1979 sequel, More American Graffiti.
In 1973, he and American Graffiti co-star Cindy Williams appeared together in an episode of Love, American Style titled "Love and the Time Machine".
More recently, he has appeared in mini-series such as P.T. Barnum, Kingdom Hospital and The Triangle as well as the feature film Lucky You directed by Curtis Hanson. In 2009, he played a featured role, Sheriff Golightly, in the second episode of season two of the TV series Fringe.
Never Cry Wolf (1983)
Smith devoted almost three years to filming Never Cry Wolf, adapted from a memoir by environmentalist Farley Mowat. Smith said, "I was much more closely involved in that picture than I had been in any other film. Not only acting, but writing and the whole creative process." He also found the process difficult. "During much of the two-year shooting schedule in Canada's Yukon and in Nome, Alaska, I was the only actor present. It was the loneliest film I've ever worked on."[5] During the filming, he became so enamored of the Northwest that he decided to relocate to Vancouver, British Columbia, where he has resided since the mid-1980s.[citation needed]
Carroll Ballard, director of Never Cry Wolf, asked Smith to write much of the narration for the film. Smith also performed in a lengthy scene with wolves and caribou in which he was entirely naked. While working on this production, Smith formed a friendship with the author, Farley Mowat, which lasted until Mowat's death in 2014.[6]
Directing
Along with his acting career, since the mid-1990s Smith has increasingly focused on his work behind the camera both as a writer and director. His first film as director was the camp horror story Trick or Treat (1986) for Dino De Laurentiis, in which he also appeared. In 1992, he directed and acted in Fifty/Fifty, a movie filmed in Malaysia which also starred Robert Hays and Peter Weller. He was one of the directors of the TV series Space: Above and Beyond (1995) as well as the director of the initial episode ("Welcome to the Hellmouth") that launched the TV series Buffy the Vampire Slayer (1997). He next directed the successful feature film Air Bud (Disney, 1997), and two TV miniseries for Hallmark Entertainment, Roughing It, starring James Garner as Mark Twain, (2001) and Icon (2005), starring Patrick Swayze, Michael York and Patrick Bergin. He directed numerous episodes of the Canadian television series DaVinci's Inquest, and wrote and executive produced The Clinic, a film about a veterinary clinic for Animal Planet in 2003.
In 2003, he wrote and directed the acclaimed Canadian feature film The Snow Walker for Lions Gate Films, based on a story by Farley Mowat, which marked a return to the Arctic for Smith and garnered nine Genie Award nominations including Best Picture, Best Adapted Screenplay, and Best Director for Smith.
He returned to write and direct the sequel, Dolphin Tale 2. He based his original script on various true-life events that have occurred at the Clearwater Marine Hospital, including the dramatic rescue of a baby dolphin named "Hope" that coincidentally happened during the wrap party of the first film, with many of the film's cast and crew watching. The entire cast returned to take part, and the movie was released by Warner Bros on September 12, 2014.
