Sigourney Weaver is in talks to join Greg Mottola's upcoming comedy "Paul," about two sci-fi freaks who encounter a real alien during a road trip to Area 51. The film also stars Seth Rogen, Jason Bateman, Kristen Wiig, Bill Hader, Jane Lynch, Simong Pegg and Nick Frost, with Rogen set to voice the alien. Variety says Weaver's role in the film would not be announced at this stage.

Weaver also recently joined the cast of Andy Fickman's upcoming Disney comedy "You Again," about a woman who discovers her brother is about to marry the girl (Weaver plays her rich aunt) who constantly bullied her in high school. Kristen Bell also stars in the film, which Dave Johnson and Moe Jelline wrote.

Weaver recently appeared in "Vantage Point" and "Baby Mama." She also did some voice work in "WALL-E" and "The Tale of Despereaux." Upcoming projects of hers include James Cameron's "Avatar" and possibly "Ghostsbusters III."

Here is your dose of film news for May 27, 2009:

• Jessica Szohr from "Gossip Girl" is set to star in Alexandre Aja's upcoming "Piranha 3-D." Elisabeth Shue, Adam Scott, Ving Rhames, Dina Meyer and Richard Dreyfuss are already cast. The film, which will open March 19, 2010, follows a group of strangers battling hungry fish in a lake. (Variety)

Yes, you read right. British actor Simon Pegg left Quentin Tarantino’s upcoming WWII drama “Inglorious Bastards” because of scheduling conflicts, according to Empire Online.

Okay, it may not hurt the project that much, but I was definitely looking forward to Pegg kicking butt as a British lieutenant.

On the other hand, however, “Superbad” director Greg Mottola is set to direct “Paul,” a road trip comedy written by Pegg and his buddy Nick Frost, whose acting credits include “Shaun of the Dead” and “Hot Fuzz.”

Not much is known about that project at this stage, but the plot centers on two buddies taking a road trip across America.

That’s good news. I strongly believe in Mottola’s ability to direct other hilarious comedies, and with Pegg and Frost supplying him with a script, what could possibly go wrong?
