Sigourney Weaver joins the cast of Paul...

...along with another project, according to this in Variety:
Sigourney Weaver has been set to star in “You Again” for Disney and is in talks to join the Greg Mottola-directed comedy “Paul” for Universal and Working Title.
Weaver will first shoot “Paul,” a comedy about two sci-fi fans (Simon Pegg, Nick Frost) who come across an escaped alien (voiced by Seth Rogen) near Area 51 and try to help it escape. Weaver, who toplined four “Alien” films, is keeping the role she plays under wraps.
She will then star in “You Again” with Kristen Bell for director Andy Fickman. Bell will play a young woman who returns home for her brother’s wedding and is horrified to find he’s marrying her high school nemesis. Weaver will play the bride’s filthy-rich aunt.
Weaver will next star in the James Cameron-directed “Avatar” for 20th Century Fox.
-Paul keeps sounding better and better...thoughts?
