"Prometheus 2" signed on Sigourney Weaver and while it's not clear what role she plays, this lends credence to theories that film is a prequel to the 'Alien' franchise. Meanwhile, speculations arise that there are problems with the creators piecing together the story which further moved back Ridley Scott's film to 2015 at the earliest.

In the "Alien" franchise, Sigourney Weaver plays Ellen Ripley, a badass of a character who was resurrected four times in the sequels "Aliens" (1986), "Alien 3" (1992) and "Alien Ressurection" (1997) where Ripley finally dies.

The connection with "Prometheus 2" to the "Alien" franchise "all but seals the deal," a source to Fangoria.

"The connection to the ALIEN franchise is getting the film fast-tracked, and the studio hopes to win back fans jaded by the tenuous connections in the first film," the source added.

The website also said that Sigourney Weaver, 64, has been hitting the gym with Bill Carter, the "trainer of the stars," to prepare for the physical nature of the character. There's no word yet as to what role she will play as director Ridley Scott is very secretive about revealing too much about the plot of "Prometheus 2."

The secret meetings between Sigourney Weaver and Ridley Scott even went so far as borrowing a boat on the set of his next film "Exodus" so they can discuss details of the film "on international waters."

Other than Sigourney Weaver, Noomi Rapace and Michael Fassbender are the only actors whom the source can confirm who will be coming back for "Prometheus 2"

In "Prometheus 2," Michael Fassbender will play multiple "David" androids, which means there will be more than one Michael Fassbender on screen at the same time, according to an individual familiar with the project," TheWrap said.

The website added that "Prometheus 2" might not be the final title of the film, which will begin production in the fall, as it's now being called as the "Untitled Ridley Scott Project."
