Last week we heard that Seth Rogen and Jason Batemen would be joining Simon Pegg and Nick Frost in Greg Mottola’s Paul. At that point I didn’t think the cast could get any better, however today is actually might.

According to The Playlist Sigourney Weaver (who will next be seen in Avatar) has joined the cast. Ripley will be once again be meeting an alien! The Playlist also have an official synopsis of the film, which will begin filming this summer.

PAUL is the story of Graham Willy (Simon Pegg) and Clive Gollings (Nick Frost), two sci-fi enthusiasts from the UK. The film follows them on a once in a lifetime trip to America, starting with a visit to San Diego Comic Con. Having enjoyed the delights of the convention, the boys set off on a trip to Area 51 for a spot of light UFO tourism. However, their trip takes a sudden and dramatic turn when the boys happen upon a crashed government vehicle containing an Alien called Paul (to be voiced by Seth Rogen). They embark upon an adventure, which sees them accidentally kidnapping a young Christian girl (Kristen Wiig) and paying a surprise visit to an old woman called Tara, who 60 years before pulled a stricken Paul from his crashed ship. Together, this mismatched band struggle to help Paul get home, all the while trying desperately to stay ahead of the tenacious government operative, Agent Lorenzo Zoil (Jason Bateman) and Ruth’s zealous, shot- gun toting, bible bashing father, Moses Behe. This is a comedy about being an alien in America, even if you’re not from outer space.
