Another possible plot?

A plot to some b movie called ALIEN AGENT released in 2007: [i]Plot: When a group of alien agents from a dying planet come to Earth under the leadership of Isis to build a portal to connect both worlds, the warrior Rykker opposes the invaders and defends the earthlings. He rescues the teenager Julie, whose family was murdered by the invaders, and together they try to destroy the portal and avoid the invasion commanded by the cruel Saylon.[/i] [url=http://www.imdb.com/title/tt0820466/]IMDB[/url] Space Jockey as the Defender? Portal to Connect Both World = wormhole plot speculation? Interviewers mentioned PROMETHEUS plot as being more "Epic"=Battle for Earth Survival?
