Natasha Henstridge (born August 15, 1974) is a Canadian model turned actress who has starred in several movies, including Species and Species II. Born in Springdale, Newfoundland to parents Brian and Helen, she was raised in a trailer park in Fort McMurray, Alberta. Her father is a contractor and her mother a housewife. At the age of thirteen, she entered the Casablanca Modelling Agency's "Look of the Year" contest and won the prize for first runner up.

The following year, Henstridge went to Paris to pursue her modelling ambitions. At fifteen, she was featured on her first magazine cover, the French edition of Cosmopolitan. Several magazine covers followed and Henstridge went on to do television commercials for products such as Olay, Old Spice and Lady Stetson. Her modelling career well established, Henstridge decided to try her luck in movies.

Her first movie Species was a box office success. Her role as a alien nymphomaniac was notable for its sexual allure.

In the sequel Species II, she played a gentler and more docile version of the alien. A few smaller movies followed, including Bela Donna, Dog Park with varied box office returns.

In, 2000 she starred in The Whole Nine Yards, which led to sequel The Whole Ten Yards, and also Ghosts of Mars. The latter was not well received, with a 21% rating on rotten tomatoes.

She has played a number of roles on television, such as Caracara, The Outer Limits and She Spies.

In her movie debut, in Species, Henstridge plays a genetically engineered human form of the DNA of an alien. She breaks from the captivity of the lab and embarks on a killing spree. A team of experts bands together to stop her. With a strong cast and an interesting story angle, Species was an instant cult hit. That year, Henstridge won the MTV Movie award for "best kiss."

This movie was a box office hit and made Henstridge an instant star in the sci-fi movie genre. The movie gave Henstridge a perfect platform to launch her acting career but she could not capitalize on it as most of the following movies failed to generate the same excitement. Species is perhaps the most successful debut movie for any model turned actress.The movie netted $60 million in North America and about $53 million overseas.

The long-awaited sequel of Species was released in 1998 by MGM-UA to much fanfare. In the film Species II, she plays a cloned version of the alien she played in Species.

Unlike its predecessor, Species II was a failure at the box-office. Undaunted, Henstridge continued to pursue various roles. Despite having some reservations about the sci-fi genre, she signed up for John Carpenter's Ghosts of Mars in the lead role.

Henstridge played the protagonist in her TV movie, Caracara, which received poor ratings. She plays a lonely ornithologist Rachel Sutherland who allows her home to become an observation post for the F.B.I., in their efforts to zero-in on a would-be assassin of a foreign president. She falls in love with one of the agents who turns out to be the assassin himself. How Rachel foils the assassination and escapes from the grip of the assassin is the subject of the rest of the story.

The following year, she played in a multilingual movie called Bela Donna which did well in Brazil and South America. In the movie, she plays a wife to an explorer who goes on a treasure hunting spree to Brazil. There she is stalked by a fisherman with whom she falls in love. What follows is a web of intrigue, betrayal and suspense. The movie received positive reviews in Brazil, where it was exclusively shot and her role widely acclaimed.

Henstridge was working on the TV show She Spies, prior to its cancellation. She has also completed a TV movie titled Widow on the hill which has received critical acclaim. Henstridge has begun taking roles in independent films to help build up her acting credibility. She is settled in L.A.'s Hollywood Hills with fiancé and sons (Tristan and Asher).

She now has a recurring role on Commander in Chief starring Geena Davis as a fictional female U.S. President.

Hestridge was married to actor Damian Chapa twice. However, the second marriage lasted only a few months. She has a son by Liam Waite, called Tristan River Waite, born October 14, 1998, and a second son Asher Sky Waite, born in September 2001.
