DVD release for Smith's last film

The last film made by model and actress Anna Nicole Smith is to be released in the US on DVD in May, distributors say.

Illegal Aliens, a low-budget, high-camp comedy was partly financed by Smith, a former Playboy model.

She stars as one of three aliens who become "super-hot babes and arrive to protect the Earth from intergalactic forces of evil", says a press release.

Smith died of unknown causes in Florida last week after being found unconscious in a hotel. She was 39.

A paternity row has erupted over her five-month-old daughter, Dannielynn, with three men claiming to be the father of the child.

Smith married Texas oil billionaire J Howard Marshall II in 1994, not long after being named Playboy's Playmate of the Year. She was 26 and he was 89.

He died 14 months later, setting the stage for a battle over his estate that pitted Smith against Mr Marshall's son.

The case has not yet been resolved, even though Marshall's son died last year.

Smith's own son Daniel died in September, leaving her daughter as her only surviving offspring.

Film role

Shot in September 2005, Illegal Aliens was Smith's last film project. She had previously featured in The Hudsucker Proxy and the third Naked Gun movie.

A spokesperson for MTI Home Video, which is distributing the film, said the timing of its release had nothing to do with the former model's death.

The company had submitted the DVD to retailers for sale about a week and a half before she died, he said, and Smith had planned to take part in a publicity campaign for the film.
