LOS ANGELES? - The last movie made by stripper-turned-celebrity Anna Nicole Smith, a sci-fi comedy titled "Illegal Aliens," will be released on DVD in May, its distributor said on Tuesday.

The film stars Smith, who died last week in Florida, as one of three aliens who transform themselves into "super-hot babes and arrive to protect the Earth from intergalactic forces of evil," according to press materials from MTI Home Video, which will distribute the movie through DVD outlets.

MTI spokesman Ed Baran described "Illegal Aliens," which is unrated, as a low-budget, deliberately "high-camp" production in which Smith lampoons her own ditsy sex-bomb image.

No release is planned for movie theaters, Baran said.

Filmmakers clearly had no Oscar ambitions for the 93-minute movie, which was shot in September 2005 in Vermont, Los Angeles and New York.

A trailer, posted on the Web site of the production company, Edgewood Studios (www.edgewoodstudios.com), shows Smith's character, Lucy, shouting, "Nobody sticks a missile in Lucy's butt and gets away with it!"

In another scene, she appears tied up to a chair and laments, "Who do I have to screw to get off this movie?"

Smith invested her own money in the project and even took part in scripting her role. Her son, Daniel, who died in the Bahamas in September at age 20, three days after Smith gave birth to her daughter, was credited as an associate producer on the film, Baran said.

"A lot of people really want to make her out to be some idiot but I really don't think that she was," Baran said. "She's poking fun at herself within the film so I think it's pretty damn smart."

The former stripper and Playboy magazine centerfold died Thursday of unknown causes while enmeshed in a paternity suit over her infant daughter and a long-running dispute over the fortune left by an elderly oil tycoon she married in 1994.

Smith, who was 39, previously starred in her own cable TV reality series, "The Anna Nicole Smith Show." She appeared a handful of movies, beginning in 1994 with "The Hudsucker Proxy" and the big-screen spoof "Naked Gun 33 1/3: The Final Insult."

Baran said the timing of distribution of Smith's last film was coincidental to her death, with MTI having submitted it to retailers for sale this coming spring about a week and a half before she died. Smith had planned to take part in a publicity campaign for the film, he said.
