Roadside Attractions has acquired US theatrical rights to RW Goodwin's homage to 1950s sci-fi alien invasion films, Alien Trespass.

The film stars Will & Grace's Eric McCormack in his first leading film role since leaving the series and will receive its world premiere at the 2009 Palm Springs International Film Festival in January.

Roadside will release the film theatrically in 22 markets on April 3. Set in 1957, Alien Trespass is about a spaceship that crashes to Earth and deposits two aliens; one that wants to rule Earth while the other inhabits an astronomer's body and sets out to save mankind.

Jenni Baird, Dan Lauria and Robert Patrick round out the key cast. The film is based on a story by James Swift and Steven Fisher and screenplay by Fisher and was produced by Swift and Goodwin.

'With Alien Trespass, RW has created something really unique,' Roadside co-president Howard Cohen said. 'Not only does the film effortlessly juggle sci-fi, comedy, drama and suspense, but its visual style masterfully revives the bright, Technicolor look of the era.'

Greg Bernstein of Greg S Bernstein - A Professional Corporation negotiated the deal on behalf of Roadside Attractions with Gary Barkin of Barkin Smith on behalf of the film-makers.
